    Spatial density distribution of Ta atoms in the first CDW phase of 2H-TaSe2 obtained by mapping a 120 Å × 120 Å × 120 Å RMC-refi Picture solar materials in which defects do not damage photovoltaic efficiency; catalysts whose surfaces retain activity even in the presence of corrosive chemicals; or sensors immune to noise from the environment.

    Any one of these is a revolutionary achievement; the excitement is that quantum materials are known to contain the necessary ingredients to make each of these possible in real devices.

    Using high-energy x-rays provided by the Advanced Photon Source of the Argonne National Laboratory, researchers from CMU studied the quantum material TaSe2 exhibiting charge density waves, an ordered quantum fluid of electrons forming a standing wave pattern.

    The studies found that the waves emerge near room temperature and grow with decreasing temperature before becoming frozen in space at -300 Fahrenheit.

    The results shed light on the unusual electronic properties of TaSe2, including the appearance of superconductivity at about -455 Fahrenheit.

  • CMU Physics Faculty Member Awarded Federal Research Grant
    Juan PeraltaCMU physics faculty member, Juan Peralta, was recently awarded a $271,000 research grant by the U.S. Department of Energy.

    This is a continuation of a grant previously awarded to Dr. Peralta that will allow a Ph.D. student to work along side Dr. Peralta to develop computational tools for materials discovery.

    Physical and chemical processes and material properties are critical for energy applications such as catalytic processes involving transition metals or the properties of nanoparticles used to increase the rate of oxygen reduction to water in fuel cells.

    To drive innovation in these areas, it is of paramount importance to understand the properties of these materials.

    Here is where Dr. Peralta’s first-principles computer simulations derived from fundamental quantum mechanics play a key role as tools to predict new phenomena, determine the material's parameters needed for modeling its behavior, and, more generally, analyze experimental results.
  • Comet C/2020 F3 Neowise, July 12, 2020
    screenshot of youtube video This month we are treated to one of the brightest comets in more than 20 years. Discovered on March 23, 2020 by NASA's NEOWISE space telescope (after which the comet is named), it made a close approach to the Sun on July 3, closer even than planet Mercury.

    Unlike many other comets, this one survived the Sun's intense heat and developed an impressive dust tail, along with a fainter, blue gas/ion tail.

    For the next few days, the comet will be visible to the naked eye at around 11 pm in the northwest sky. You will need a low horizon, unobscured by buildings and trees, and a reasonably dark sky. Using a pair of binoculars or a small telescope will make the tail stand out better.

    This video, created by CMU Physics faculty member Axel Mellinger, is a time lapse made from 327 individual, 2-second exposures, taken over a 35 minute time span with a Canon 6D DSLR camera and a telephoto lens from a parking lot on the west side of Mt. Pleasant. The comet's motion in the video is actually due to the Earth's rotation.

    Don't miss comet NEOWISE, since it will not be back for another 6,800 years!

  • Nailing down water?
    Dr. Chananate Uthaisar receiving the 2019 BrightVolt Employee of the Year awardWater is paramount in nearly all areas of science. Yet, computational methods that are remarkably successful in predicting the properties of many materials, fail for water. A team from CMU in collaboration with Temple University and University of Texas at El Paso showed recently that removing the so-called self-interaction error, which is an artifact that is intrinsically embedded in popular computational methods, helps to improve the description of water. This work is part of a large collaborative effort to advance computational methods that help understand the fundamental properties of molecules and materials.

    CMU, Clemson students compete in first-ever online Astro-hackathon
    Matt Redshaw in front of testing equipment Last week, CMU and Clemson faced-off in the first Astrophysics-themed hackathon event.

    For 3 days straight, teams from the two Universities battled it out virtually, coding their Astrophysics and Nuclear science knowledge into meaningful calculation tools. In the process, they broadened their physics and coding knowledge and produced some interesting results that are worth using for their future research.

    The competition had a simple goal: "Use webnucleo (nucleosynthesis toolkit developed by Clemson) for an application of your choice in nuclear astrophysics" The competing projects were judged based on their originality/creativity, visual quality/presentation, the usefulness within the science of nuclear astrophysics, and the technical difficulty of the work.

    When all code was done and results presented, one of the CMU teams emerged victorious with their Grand-prize winning project simulating a neutron star devouring a white dwarf star. A Clemson team received the special prize for best visual presentation with their project simulating the dramatic explosion of a white dwarf into a type Ia supernova, while a second Clemson team received the special prize for technical difficulty with a project simulating fine details of the mechanism of chemical element formation in supernovae and burning stars.

    Matt Redshaw in front of testing equipment “What I love most about it, is that I get to do a lot of different things. I get to teach and mentor students, from first year undergraduates just starting out on their physics journey, to PhD students who are developing the skills to start on their careers as independent scientists.” said Matt Redshaw, Associate Professor of Physics at Central Michigan University.

    “I also get to think about interesting problems and ideas in physics, and to plan and run experiments to help solve those problems and test those ideas.”

    Redshaw recently spent some time with Futurum magazine describing his current research, testing Einstein’s Theory of Relativity, and sharing his path to a career in nuclear physics.

    “I learned that it is nuclear physics that fuels the life and death of stars. I think it is really cool that by studying the laws of physics that describe how the tiny nucleus of an atom behaves, you can understand the universe on a galactic scale,” said Redshaw.

    Supernovas, Burning Stars, & X-ray Bursts..Oh My
    First Hands-on Coding Workshop a huge success

    Images of the progression of a supernova On February 6th, CMU Physics students, tested their skills simulating burning and exploding stars, in the first-ever hands-on coding workshop on the creation of elements, organized at the CMU Department of Physics.

    The challenge was simple: Choose your favorite type of cosmic event (Supernova, Burning star, X-ray burst, etc).; Hack your way through a specialized set of codes to build a realistic simulation of the explosion. Make visuals of the results. Impress your friends and colleagues.

    The one-day event was a collaboration between Central Michigan University and Clemson University and is the first of a series of events planned between the Physics departments of the two Universities.

    The goal is to provide students hands-on specialization using the latest coding toolkits available in a niche subfield of physics and prepare them for success in graduate school and research-related careers.

    Everybody had a blast and learned a lot. The students particularly benefited by having the creator of the coding package, Prof. Brad Meyer from Clemson University in the same room coaching them.

    The next event in the series, a friendly online face-off between Clemson and Central Michigan student teams, is currently planned for later in the Spring semester.

    CMU researcher cashing in on gold
    Tiny gold nanostructures show huge potential

    Physics Graduate Student in LabSince ancient times, gold has been used in the production of jewelry, coins, statues…even as decoration for buildings. Today, gold nanostructures, in particular thin gold nanowires, are attracting a lot of interest due to their potential in the fields of catalysis, molecular electronics, bioimaging, and drug delivery.

    While interest in these nanostructures is high, the details of their formation is still undetermined. Recently CMU physics researcher Valeri Petkov, along with researchers from France, have grown long gold nanowires at the Argonne National Laboratory outside Chicago.

    “If we know how they grow, we can make them by smart design,” said Petkov.

    In the future, gold nanostructures could aid in speeding up chemical reactions, help target the delivery of medications, creating molecular building blocks for electronic components, even help to non-invasively view biological processes in real time.

    Physics chases ‘ghost particles’
    Team is building a more accurate device to measure the mass of the elusive neutrino

    Physics Graduate Student in Lab ​Central Michigan University physics faculty member Matt Redshaw and his students are proud to be making a big deal of almost nothing.

    They are working to help determine the precise mass of neutrinos, the "ghost particles" of the universe that for many years scientists didn't even know existed because their mass is near zero. Billions of them are thought to have been born during the Big Bang, and knowing their mass would contribute to theories of how the universe evolved, Redshaw said.

    "There are enough of them that they can exert a gravitational influence on the universe," he said.

    But because they are so tiny, measuring their mass has proven nearly impossible. The best measurement that scientists have been able to make is putting upper limits on its mass. The most recent measurement, made in September in Germany, said it can't have mass of more than 1.1 electron volts, or about one five-hundred-thousandth the mass of an electron.

    Improving our picture of molecules
    CMU physics undergraduate is lead author on published paper

    Alex JohnsonAlex Johnson, a senior physics major from Brownstown, MI, is first author of a new article being published in the Journal of Chemical Physics, a journal that has been publishing top research in the area of chemical physics since 1933.

    The article documents how a new correction to density functional theory (DFT), a popular method that allows the properties of molecules and solids to be predicted computationally, significantly improves the description of a molecule’s electric dipole moment. This key characteristic determines the forces molecules exert on one another and computing it accurately is essential for modeling chemical processes.

    Alex designed the statistical tests for the study, which was crucial for this work. He carried out the calculations using the high performance computing resources at the Institute for Cyber-Enabled Research (ICER) at Michigan State University. (CMU is an ICER partner institution.) He and his co-authors in the Physics Departments at CMU and the University of Texas at El Paso are members of the FLOSIC Center, a research center funded by the U.S. Department of Energy and devoted to improving DFT.

    Three CMU physics researchers
    Are using quantum computers to help meet demand for more powerful tools

    “A classical computation is like a solo voice—one line of pure tones succeeding each other. A quantum computation is like a symphony—many lines of tones interfering with one another” (S. Lloyd).

    And this quantum symphony is potentially able to accelerate computer technology beyond what we can currently imagine. Three researchers in CMU’s Department of Physics, Dr. Andrew Supka, Dr. Virginia Carnevali, and faculty member Marco Fornari, have received funding from the Department of Energy to embark upon this great adventure: learning how and which kind of “symphonies” can be composed and played with a quantum computer, specifically a D-Wave Quantum Computer.

    The topic is hot, but the task is hard! Virginia’s work aims to apply quantum computation to simulate how electrons travel in complex systems.

    Andrew is implementing algorithms to harness the power of quantum computing for machine learning and artificial intelligence.

    Expressing the problems in the D-Wave language is the first step then, through the phenomenon of quantum annealing, the computer seeks the solution in the quantum realm.

    The computational scientific community is increasingly demanding more powerful tools: quantum computing is the strong candidate for the future, and we are proud to contribute on writing “new symphonies” for science.

    The mystery of the neutrino mass came one step closer to solution in September. Physics is building lab to enable closing in even more
    Matt Redshaw and the Chip Trap he is buildingThe strange and ghostly neutrino has intrigued physicists since it was first theorized to exist nearly 90 years ago. Back then, people thought the neutrino had no mass, similar to photons, the particles of light. We have learned much about the neutrino over this time. (Neutrinos come to us from space, or from earth created by human or born out of radioactive decay of some materials). We now know that neutrinos come in three flavors! Each neutrino flavor interacts differently with the world than the other.

    And that's not all! Experiments showed that as neutrinos fly in space, they continuously swap between their three flavors. Think about it! A neutrino starts as one type of particle and continually changes into a different particle and back again. Physicists have found that to do this flavor swapping (called neutrino oscillation) neutrinos can not be massless, as was previously thought. The physicists that made this discovery earned the 2016 Nobel Prize in physics.

    Still, we don't know yet exactly how much mass each neutrino has. Neutrino oscillation experiments show that neutrinos have mass, not what these masses are. Over the years, physicists have put down an enormous worldwide experimental effort to find the answer (the "absolute neutrino mass scale" in physics terminology). The most stringent of these investigations study how much energy is turned into neutrino mass during radioactive decays that generate neutrinos. They study neutrinos born during the beta-decay of isotopes such as tritium, the heaviest isotope of hydrogen on earth. Measurements of this consumed energy from the 1990s and 2000s have set an upper limit on the neutrino mass to be 2ev/c2, approximately 255,000 times lighter than an electron, which is the next in order lightest fundamental particle, with a mass of 511,000 eV/c2.

    In September 2019, the next-generation tritium beta-decay experiment for neutrino mass determination, KATRIN, in Karlsruhe, Germany, lowered this upper limit by a factor of two, to 1 eV/c2, i.e., 511,000 times lighter mass than the electron (read about it here).

    Experiments such as KATRIN, cannot measure the neutrino mass unless they know the total energy released in the radioactive decay that produces the neutrinos. For KATRIN, according to Einstein's theory of relativity, this energy is equal to the mass difference between tritium and helium-3 (what tritium becomes after the decay). This mass was precisely measured at Florida State University where Prof. Redshaw received his Ph.D. in 2007. The Florida group used a Penning trap – a device that can trap isotope ions inside strong magnetic and electric fields.

    Prof. Matt Redshaw is one of the Physicists working on an even more improved generation of experiments for a more precise measurement of the neutrino mass. One that will use the beta-decay of the radioactive isotope holmium-163. Matt and his graduate and undergraduate students have designed and are building an advanced Penning trap at Central Michigan University that is called CHIP-TRAP. It will precisely measure the energy released in the holmium-163 beta decay opening the road for a further reduction of the upper limit on the neutrino mass.

    Would like to hear all the latest news on the search for the neutrino mystery mass? Join us on Thursday, October 3rd at the Physics department colloquium, where Prof. Diana Parno from Carnegie Mellon University and member of the KATRIN collaboration, will talk about the new results from KATRIN, as well as plans in the community for neutrino mass determination experiments with other isotopes, such as 163Ho.

    CMU Researchers Praised for Publication
    The world of minerals has many surprises. Searching for cheaper and non-toxic materials that provide high performance without compromising the environment is of paramount importance and complex minerals may be key to sustainable novel technologies.

    CMU researchers Andrew Supka, Rabih Al Rahal Al Orabi, and physics faculty member Marco Fornari, working in collaboration with experimental groups in France and Japan, have discovered ways to improve the properties of mineral Colusite to make it more efficient in transforming waste heat into useful electrical energy.

    Research in thermoelectric energy conversion has led to things such as mini-refrigerators, the source of energy that has kept the Voyager spacecraft alive since 1977, and devices that recover thermal energy losses in the automotive sector.

    The editor of the international edition of Angewandte Chemie wrote: "According to the evaluation of referees the results reported in your Communication are “highly important” or even “very important”.

    His research, supported by grants from the Department of Energy, proposes a method, based on machine learning, that “allows us to do a very quick evaluation of the voltage that a material will provide in a battery,” said CMU physics faculty member Juan Peralta. “Previously, testing materials was time consuming and expensive.”

    If a new material is found to provide useful a voltage, scientists and engineers can use that material to create new battery technologies, thus Rajendra Joshi’s work allows for quicker and cheaper development of real world devices such as laptop computers and cellular phones.

He wanted a job. "But I didn't know what I was doing: writing a resume, a cover letter, trying to get an interview," he said. "I was just sitting at my kitchen table, opening job applications, filling them out and sending them off." He said he applied for about 50 positions. "I heard back from one, which told me that I wasn't qualified and asked me if I knew someone who was. It was demoralizing."

    Seeking keys to the universe
    CMU team runs experiment at superconducting cyclotron to help solve nuclear puzzle
    Alfredo Estrade at the cyclotronWhen two neutron stars collided in 2017 in a never-before-seen event, astronomers and astrophysicists were in seventh heaven, so to speak. Nuclear reactions from the exploding stars rained cosmic debris thought to be the source of gold, silver, platinum and uranium ­­­— heavy elements that astrophysicists say have enhanced the chemical composition of the universe. "My wedding band emerged from a neutron star merger," ScienceNews quoted Harvard theoretical astrophysicist Avi Loeb at the time. Understanding the conditions that create chemical elements is the goal of physics instructors such as Central Michigan University assistant professor Alfredo Estrade. But reproducing on Earth how these and other elements are created in the nuclear reaction of a stellar explosion is impossible — unless each step in the chain is studied separately, he said. To do that, a team of CMU faculty and students recently ran its experiment at one of the world's flagship nuclear science research facilities — the National Superconducting Cyclotron Laboratory on the campus of Michigan State University.

  • LIGO uncovers the birthplace of gold and other heavy elements in the death spiral of neutron stars
    Recent discoveries fuel CMU research
    By Dr. Alfredo Estrade & Dr. Georgios Perdikakis / Photo courtesy of NSF/LIGO/Sonoma State University/A. Simonnet
    Black Hole collision When the history books are written, the past year in physics will be one remembered by violent cosmic events and the birth of a new type of astronomy – one based on gravitational waves.

    It all started in 2016 with the first detection of a collision between black-holes by LIGO, the Laser Interferometer Gravitational-wave Observatory. As a result, the pioneers behind LIGO's development, Rainer Weiss, Kip Thorne, and Barry Barish, where awarded the 2017 Nobel Prize in Physics. LIGO allows us for the first time to feel --actually hear by means of an actual audible chirp-- the ripples caused to the very fabric of space time when compact objects such as massive black holes and neutron stars many times the mass of our sun merge spiraling into each other.

    But that discovery was just the tip of the iceberg. This week a collaboration of LIGO and other observatories announced the discovery of a merger between two neutron stars, a very exotic cosmic event that had long been predicted by astrophysics theories but never observed. In August 17th, just as the USA was preparing for a solar eclipse, a gravitational wave signal was felt by both LIGO and a similar European observatory (VIRGO), at the same time as a burst of gamma-rays was observed by the Fermi gamma-ray telescope. It looked like a neutron star merger event, so it triggered an alert for a number of survey telescopes that frantically started scanning the sky to find a smoking gun. When a new shiny bright object was found a few hours later in a galaxy far far away (NGC 4993), the astronomy community went into overdrive and every respectable telescope was pointed in that direction!

    A neutron star is likely the most dense and hard and stiff object in the universe; the mass of a star like the sun all packed into a sphere the size of Mount Pleasant! Scientists have long suspected that many of such beasts are not alone, but spend their life dancing around another neutron star partner for millions of years until their orbits become so close that they merge in a violent cosmic collision. After the ripples of the collision where detected by LIGO, optical telescopes observed a beautiful display of cosmic fireworks that shone 200 billion times brighter than our sun and quickly faded away in about a week: the fascinating event was baptized a Kilonova.

    The observation of the neutron star merger is a treasure of data to test physics and astrophysics theories, ranging from cosmology to nuclear physics question. One of the most important pieces of information relates to the origin of the chemical elements in our world, and has CMU Professors Alfredo Estrade and George Perdikakis (and the rest of the nuclear astrophysics community) particularly excited. Astrophysicists had long speculated that during a merger the conditions would be just right so the material spewed out by the collision – mostly neutrons – would rearrange itself in an act of stellar alchemy to create most elements beyond Tin in the periodic table. So astronomers where looking for them in the wreckage of the merger… and they found gold! Not just a bit of gold; Many Septillion - a billion quadrillions (or 10^24) - pounds of gold! Many many gold atoms in mint new condition; enough to make ten planets of pure and only gold with the mass of the earth… And not just gold; also the iodine of your Thyroid, the lead that might poison your water pipes, or the uranium in the core of nuclear power plants.

    What we witnessed for the first time was a nucleosynthesis event that creates all those heavy elements that, after being ejected into the interstellar medium, will be recycled into new planets and stars, in a continuous cycle of galactic chemical evolution. This has confirmed that the bizarre theories about how the elements are formed might actually be correct! It will allow nuclear astrophysicists to test many details about theories on the origin of the elements – for example how the nuclear reactions that Prof Estrade and Perdikakis measure with experiments at accelerator labs contribute to the formation of gold and other heavy elements – and likely discover new surprises along the way.

Experimental and theoretical nuclear physics, astrophysical models, astronomical data, or atomic physics experiments, are some of the fields that contribute to our understanding of the stellar processes that enrich the chemical composition of the universe. This expertise is often scattered across distant institutions, and even different countries, and international workshops and conferences are essential to keep the field moving forwards. In recent months three graduate students from Central Michigan University had the opportunity to participate in such meetings. Panagiotis Gastis, and Stylianos Nikas attended the Astrophysical Nuclear Reaction Network School in Schmitten, Germany, to learn about modern computational tools in nuclear astrophysics. Neerajan Nepal participated in the Joint JINA/CEE Winter School on Nuclear Astrophysics in Shanghai, China, which aimed to bring together young researchers in the field from the US and China. Both of them presented talks about their research projects in these meetings. It was an enriching experience, not only through learning of new scientific tools and topics that apply to their own research projects, but also from the opportunity to expand their network of fellow scientists around the world.

  • Understanding the cosmos
    CMU physicists can benefit from monumental discovery
    Last Thursday, humanity made one significant step forward in the understanding of the cosmos. Scientists from the California Institute of Technology, Massachusetts Institute of Technology and Louisiana State University announced that in September 2015 they detected, for the first time, the ripples in space-time created by the dramatic collision of two black holes 30 times the mass of our sun. Gravitational waves, as these ripples are scientifically known, were first suggested by Albert Einstein in his general theory of relativity about a century ago, in 1915.

The discovery was hailed as one of the greatest physics victories in more than 100 years, and a Central Michigan University faculty member played a key role in illustrating the finding.

  • CMU researchers study isotopes at national superconducting cyclotron
    In February 2015, CMU M.S. physics student Adam Bryce and physics professor Matthew Redshaw participated in an experiment at the National Superconducting Cyclotron Laboratory to measure the atomic mass of two radioactive carbon and oxygen isotopes. The isotopes that were studied have fewer neutrons than the stable carbon and oxygen atoms found in nature, so only live for a few minutes after they are created with the cyclotron accelerator. However, this is enough time to catch them in an ion trap and measure their atomic mass to a precision of a few parts-per-billion. The results have been used to study the so-called superallowed beta-decays that these isotopes undergo and contribute to tests of fundamental theories in physics, including the Standard Model of particle physics. The results were recently published in two papers in the high-impact physics journal Physical Review Letters.
