LEXINGTON, Ky. (May 5, 2023) — Walking across the commencement stage and receiving your diploma is a satisfying feeling and is the culmination of a lot of hard work. University of Kentucky graduate Gabija Ziemyte’s family will celebrate her accomplishments for the first time in the United States.

“My parents are from Lithuania, and they both earned master's degrees there,” said Ziemyte, a Lewis Honors student and Chellgren Student Fellow who majored in physics and mathematics with an English minor in the College of Arts and Sciences. “I think my parents are proud that I've been

LEXINGTON; Ky. — Moiré electronics are hot topics for theoretical physics. Ganpathy Murthy, professor of physics and astronomy in the University of Kentucky’s College of Arts & Sciences, spoke about the upcoming van Winter Lecture and about guest lecturer Ashvin Vishwanath, a theoretical physicist specializing in the study of condensed matter at Harvard University. 

Vishwanath is a condensed matter theorist who studies collective phenomena in quantum systems. His previous research has explored the central role of "hedgehog" defects in phase transitions, the occurrence of distinctive surface states in Weyl semimetals, Dirac fermion dualities and the notion of surface topological order.  

His attention is focused on unraveling the mysteries of moiré materials and exploring ways to create highly

Results from two separate research studies, led by University of Kentucky postdoctoral scholar Valeria Olivares and graduate student Arnab Sarkar, will be presented during the American Astronomical Society’s (AAS) semiannual meeting, taking place in Pasadena, California, this week.

As the largest astronomy conference in the United States, the AAS meeting will bring together more than 2,000 astronomers, educators, students and journalists to highlight the nation’s most groundbreaking work in the fields of physics and astronomy.

“Approximately 30 works from around the world are being highlighted at the AAS press conference, representing some of the highest impact findings of this year,” said Yuanyuan Su, assistant professor in the UK Department of Physics and Astronomy and faculty mentor to

Free-free scattering is the scattering of a free electron by an atom in the presence of, for example, a laser beam — the free electron may either absorb or emit one or more photons from the beam. (A free electron cannot absorb or emit photons without the presence of an atom because both energy and momentum cannot be conserved; the photon is a "relativistic" particle traveling at the speed of light!) The term free-free scattering is used since the electron is free (not bound to the atom) both before and after the event. The absorption or emission of radiation by charged particles during collisions with atoms and molecules has long been known to be important in astrophysical and electrical plasma phenomena. Free-free transitions are also known to dominate the radiation transport in

I have always been fascinated by the “spins” of subatomic systems, specifically the spins of atomic nuclei and their constituents. Although a spin is an intrinsic property of a fundamental particle, like its mass or charge, Nature exhibits remarkable spin-related phenomena. For example, protons and neutrons are composed of a multitude of structureless, or point-like, particles called quarks and mediators of the strong force, called gluons. The total number of quarks and gluons is completely unknown at any instant since it can vary due to quantum fluctuations. Quarks are spin-1/2 particles and the spin of gluons is 1 (in units of hbar). Since these fundamental constituents are confined to a tiny volume, it implies that the particles are highly relativistic and therefore possess

As far as we know, almost all natural phenomena stem from four fundamental interactions: electromagnetism, weak interaction, strong interaction, and gravity. The first three are governed by the laws of quantum mechanics. It is natural to think that gravity should also be governed by quantum mechanics. However ever since Einstein discovered the laws of gravity in 1915, reconciling gravity with quantum mechanics has been famously problematic.

One reason for this difficulty is the following. The other forces can be understood as processes happening in a fixed space-time background, where spatial distances and time intervals are fixed once and for all. For example, light is an electromagnetic wave which propagates

Ryan MacLellan joined the University of Kentucky as an assistant professor of physics in early 2020. Ryan was an assistant professor at the University of South Dakota for the five years prior.

Originally from Nova Scotia, Canada, Ryan received his Ph.D. on the energy calibration of the SNO experiment in 2009 from the Queen’s University. He went on to do a postdoc at the University of Alabama and then was a research associate at SLAC National Accelerator Laboratory before moving to the University of South Dakota in 2014. The discovery of neutrino mass by the SNO experiment, earned his Ph.D. supervisor Art McDonald a share of the 2015 Nobel Prize in Physics; and Ryan, along with the rest of the SNO Collaboration, a share in the 2016 Breakthrough Prize in Fundamental Physics.

His primary research interests remain

Anyi Li, 2003

Nineteen years ago, in summer 2003, I landed in the Bluegrass Airport. Lexington and the University of Kentucky then became my home until I graduated in the summer of 2009 with a Ph.D. in Theoretical Nuclear Physics under the direction of Professor Keh-Fei Liu. Now, I am an attending physicist and the chief of the Department of Medical Physics at Memorial Sloan Kettering Cancer Center in New York.

It has been quite an exciting and unique journey since I graduated from UK with a master's and Ph.D. in Physics. I began with a two-year postdoctoral training program at Duke University and continued with another two-year research associate position at the Institute for Nuclear Theory at the University of Washington. After that, I shifted my interests and became a senior software engineer at the Yahoo data

LEXINGTON, Ky. (Feb. 9, 2022) — Less than two months ago, NASA, in coordination with the European Space Agency and the Canadian Space Agency, launched the James Webb Space Telescope into its 1.6 million-mile journey away from Earth. The project, nearly 30 years in the making, is designed to see some of the first stars and galaxies that were formed in the universe.

Since it launched, the space agency has been working to get the telescope unfolded, aligned and powered up — a meticulous process that continues to see success after success. Just this week, the telescope detected its first photons from a distant star.

The Physics and Astronomy Department has welcomed Bill Gannon as assistant professor of Physics and Astronomy in the fall of 2019 after postdoctoral fellowships at Stony Brook University and Brookhaven National Laboratory, Texas A&M University and the University of British Columbia.

Gannon received his B.S. degree in physics from the University of Michigan and his Ph.D. from Northwestern University. He is originally from Alexandria, Virginia, just across the Potomac River from Washington, D.C.

Gannon’s primary research interests are in the synthesis of materials with interesting quantum magnetic properties, which he studies using neutron scattering. Interactions among electrons in a material can lead to a variety of magnetic properties that cannot be understood by considering each individual electron on its own. Of particular interest to Gannon are those whose

Experimental scientists at UK faced setbacks during the pandemic, and none more so than experimental physics, where the loss of hands-on time in laboratories is especially difficult to overcome. To protect the health and safety of students, faculty and staff involved in experimental research, the University established a four-phase plan for resumption of research, from the most restrictive (phase 1, March-June 2020) to the least restrictive (phase 4, begun in April 2021), when 70-100% of normal activities resumed. We visit the labs of Professors Gannon, Martin, Plaster and Seo to learn how they pressed forward to re-create the lab experience for their students while adhering to health and safety protocols.
