Jake Gamsky as a student

After my baseball career down the road at the road at Georgetown College fizzled out, I transferred to UK in the fall of 2009. This change brought me to the UK’s Physics and Astronomy department and changed the trajectory of my career. I participated in some exciting astronomy research with Dr. Wilhelm at the McDonald Observatory in Texas, I struggled through Dr. Gardner’s quantum class , presented research at a conference in Hawaii, and received funding to attend the International Space University through UK’s Huffaker Scholarship and the American Astronautical Society Scholarship. 

After graduating in 2011, I had a brief internship working on Space Policy at the Commercial Spaceflight Federation in Washington, DC. Once that was completed, I packed my bags and spent the summer at the International Space University (ISU) in Graz, Austria.

I joined the Department of Physics and Astronomy at the University of Kentucky as a graduate student in the fall of 1993. I arrived there after a gap of about four years after my undergraduate studies. I graduated from the University of Bucharest, Romania, in 1989, the year of the great transformations in Eastern Europe that followed the fall of the Berlin Wall. Before that time, the very idea of studying abroad was an inaccessible dream for most people in my country because of the near complete interdiction to travel abroad imposed by the dictatorship. So, the simple fact that I found myself in Lexington, KY, USA, on a university campus to embark on Ph.D. studies, felt very special and almost miraculous to me. 

I had a broad interest in theoretical high-energy physics, but I was not really focused on a particular topic. After some exploration, I

Before entering the University of Kentucky in the fall of 2010, I had some prior exposure to experimental condensed matter research but knew I had much to learn for understanding its intricate theory. So, I focused on my coursework for the first year and a half in graduate school and was fortunate to have both incredibly knowledgeable faculty and a strong supportive group of peers that enriched the educational journey. By the summer of 2012, I decided to join Prof. Ambrose Seo’s thin film oxides lab. I was specifically interested in the emergent phenomena stemming from the strong spin-orbit coupling inherent in 5d transition metals. In addition to the strong spin-orbit coupling term, the ground state of 5d transition metal oxides is highly amenable to electron-electron correlation, an experimentally tunable parameter. The

Assistant Professor Ryan Sanders joined the Department of Physics and Astronomy in the fall of 2023.  He completed a B.S. degree in physics at the University of Louisville in 2012.  He received his Ph.D. in astronomy from the University of California, Los Angeles, in 2018 before moving to the University of California, Davis, as a postdoctoral scholar.  In 2020, Dr. Sanders was awarded a prestigious NASA Hubble Fellowship which he held at UC Davis until he joined the University of Kentucky in 2023.

Dr. Sanders’s research program focuses on understanding the population of galaxies in the Universe, their origin, and the physical mechanisms that control their change and growth over time; a field of astronomy known as galaxy formation and evolution.   Some open questions in this field include: What physical mechanisms control galaxy

Chunli Huang

Chunli Huang brings a rich background in theoretical condensed matter physics from around the globe. Born in Taipei, Taiwan, and raised in Malaysia, Huang earned his Bachelor of Engineering degree in Material Science and Engineering from the National University of Singapore and completed his Ph.D. at National Tsing Hua University, Taiwan. He held two postdoctoral positions—first at the University of Texas at Austin under a Ministry of Science and Technology fellowship from Taiwan, followed by a one-year stint at Los Alamos National Laboratory.

Huang's research primarily focuses on theoretical approaches to uncover new phenomena and states of matter in condensed matter physics. He has substantial experience in areas such as magnetism, superconductivity, effects of disorder in two dimensional materials. One unique aspect of his pedagogical approach includes

With the recent retirement of Professor Keh-Fei Liu (see the Chair’s welcoming remarks in the Spring 2023 newsletter), it is apropos to reflect on some of the history of the lattice QCD group at the University of Kentucky, which formed upon his partnership with yours truly who joined the department’s faculty in 1989. Within the past decade or two, most of our lattice QCD work has been done within the international χQCD collaboration, which has been comprised mostly of our current and former postdocs and students, and their postdocs and students, who are in faculty and postdoc positions across the U.S., Europe, and Asia.

LEXINGTON, Ky. (March 29, 2024) — On Monday, April 8,sky gazers across North America will be treated to a total solar eclipse. During a solar eclipse, the moon passes between the Earth and the sun, casting a shadow on the planet and temporarily blocking the sun's light. Weather permitting, this event creates an awe-inspiring display as the sky darkens and the sun's corona becomes visible.

Like the rest of the continent, the University of Kentucky and Lexington are gearing up for this rare natural phenomenon. However, it's important to note that Lexington will only experience approximately 97% coverage. While that might sound good enough, experts in the UK Department of Physics and

As humans search for intelligent life–or any life at all—in the universe, they’re using their own intelligence to craft new ways of exploring galaxies. They’re even starting to use artificial intelligence, itself a new frontier, to deepen science’s understanding of what lies beyond.

That’s where Yuanyuan Su, an assistant professor in the Department of Physics and Astronomy, is applying her own intelligence. She and her group are using artificial intelligence to analyze images gathered from the space and ground telescopes to figure out what’s actually there.

Su has received the 2024 Early Career Prize from the High Energy Astrophysics Division of the American Astronomical Society. The

Professor Susan Gardner was awarded the University of Kentucky’s Albert and Elizabeth Kirwan Memorial Prize. The prize is bestowed each year to a faculty member in recognition of their outstanding contributions to original research or scholarship, with an emphasis on work produced four years prior to the award. Below is Professor Gardner’s description of her recent research. 

I thank my faculty colleagues for recognizing my research accomplishments with the 2022 Albert and Elizabeth Kirwan Memorial Prize. My research concerns the theoretical investigation of "fundamental symmetries,'' and their violation, to the end of identifying and interpreting new physical phenomena. In the last years,

In 2023, Professor Gary Ferland, already a Fellow of the American Astronomical Society, was named a Fellow of the American Association for the Advancement of Science, the first member of our faculty to receive this honor.  AAAS cited his development of the synthesis code “Cloudy”, which is used to simulate spectra of astronomical objects.  Gary wrote the following overview of astronomy at UK and the role of Cloudy.

David Hume (B.S. ’02) attended graduate school at the University of Colorado Boulder (CU) and conducted his Ph.D. research in (future Nobel laureate) David Wineland’s lab at the National Institute of Standards and Technology (NIST) in Boulder. After a post-doc appointment at the University of Heidelberg, he returned to NIST to continue his research on high precision measurements of trapped ions, in particular the use of aluminum ions as atomic clocks.

Physics seniors and Society of Physics Student officers Anthony Kelly and Gabija Ziemyte had the opportunity to ask Dr. David Hume a few questions when he visited the University of Kentucky to give a departmental colloquium in November of 2022. Below are edited excerpts from Anthony

I joined the University of Kentucky’s Department of Physics and Astronomy in the fall of 2008 as a Ph.D. student. From the very first day, it was a wonderful journey for me as an international student, and the department helped me tremendously to shape my academic career as a particle physicist alongside making long term, solid friendships.

Currently, I am a Assistant Professor in High Energy Physics at the University of Southampton in the United Kingdom. At the University of Kentucky, I pursued theoretical particle physics, precisely lattice QCD under the supervision of Professor Keh-Fei Liu. Lattice QCD provides a successful first-principles, highly computational framework to study the dynamics of quarks and gluons, which are subatomic fundamental particles glued together by a strong

Dr. Emily Bittle, 2023

When joining the University of Kentucky physics department as a graduate student in 2006, I knew that I enjoyed doing experimental research but had not yet settled on a research topic. With the wide variety of research topics being pursued at UK, it was an ideal place to spend my first two semesters learning more before starting my research in the summer of 2007 in Dr. Joe Brill’s lab. What caught my interest was electrical conduction through organic molecular materials, which was the topic of my research for my Ph.D. and which I continue to study as a physicist at the National Institute of Standards and Technology (NIST) in Gaithersburg, MD.

Scientific Basis for Time Reversal Violation in Astrophysics

Time reversal (T) symmetry of the fundamental particles and interactions of Nature would imply that replaying any motion backwards from the final conditions would cause the system to “retrace its path” back to a time-reversed version of its starting condition.  For several decades physicists assumed time reversal symmetry, understood in this sense, applied to all microscopic physical processes.  It was therefore a major shock when indirect evidence was discovered in 1964 for the violation of time reversal symmetry [3].  So far we have no fundamental explanation for this violation of time reversal symmetry.  We do know, however, that the formalism of quantum mechanics can accommodate time reversal violation without difficulty.

Today the search for new sources of T violation is one
