Using physics to explain the transmission effects of different SARS-CoV-2 mutations

During the SARS-CoV-2 pandemic, multiple new and more transmissible variants of the virus have emerged. Understanding how specific mutations affect SARS-CoV-2 transmission could help us to better understand the biology of the virus and to control outbreaks. This, however, is a challenging task, said John Barton, an assistant professor of physics and astronomy at the...

Physicist named a fellow of the American Physical Society

Gillian Wilson, a professor of physics and astronomy, has been named a fellow of the American Physical Society, or APS, “for pioneering techniques and significant contributions to clusters of galaxies, massive galaxies and cosmology, as well as for sustained leadership in research administration, broadening participation and outreach.” Wilson is one of only seven scientists elected...

Physicist’s experiment makes ‘standard literature’

UC Riverside physicist Umar Mohideen has achieved what few physicists have in their careers: his research has made the “standard literature,” meaning it has become part of the key experiments of physics. “Since it is in textbooks, the experiment is part of the established key experiments,” said Mohideen, a distinguished professor of physics. “It also...

Equipment grant will support two labs on campus

Boerge Hemmerling and Christopher Bardeen have received an equipment grant of about $214,000 from the Air Force Office of Scientific Research, or AFOSR, for a project titled “High-Flux Source for Aluminum Monochloride with Applications in Material Science.” “We will be creating and studying a new material, made of aluminum monochloride,” said Hemmerling, an assistant professor...

Deep dive into the atomic nucleus

Miguel Arratia, an assistant professor of physics and astronomy, has received a $508,000 grant from the U.S. Department of Energy to perform experiments using the electron accelerator facility at the Jefferson Laboratory, or JLab, in Newport News, Virginia, the world’s premier laboratory for imaging the subatomic structure of matter. “We will use an intense electron...

Machine learning NSF grant will help identify physical origins of noise in LIGO

Jonathan Richardson, an assistant professor of physics and astronomy; and Vagelis Papalexakis, an associate professor of computer science and engineering; have received a two-year, $300,000 grant from the National Science Foundation, or NSF, to develop novel machine-learning methods capable of analyzing the physical origins of noise in LIGO, the Laser Interferometer Gravitational-wave Observatory based at...

Department of Energy renewal grant supports student research at Brookhaven National Lab

Kenneth Barish, a professor of physics and astronomy, has received a three-year renewal grant of more than $1 million from the Department of Energy, or DOE, to support the activities of the Nucleon Spin Physics Group at UC Riverside. Physicists have made significant theoretical and experimental progress in understanding where the total spin of the...

Fourteen UC Riverside professors receive NSF CAREER Awards

Fourteen UC Riverside faculty members have received highly coveted National Science Foundation CAREER Awards. The number shatters UCR’s record for CAREER Awards set only last year. CAREER Awards are given to faculty members to fund research that is expected to form a firm foundation for a lifetime of leadership in integrating education and research. They...

Physics graduate student receives prestigious NASA fellowship

Ming-Feng Ho, a doctoral student in the Department of Physics and Astronomy, has received a three-year fellowship from Future Investigators in NASA Earth and Space Science and Technology, or FINESST, which supports research projects designed and performed by graduate students. Ho is one of 21 students to receive the prestigious fellowship out of 196 applicants...

Physicist receives NSF grant to develop instruments for gravitational wave detectors

Jonathan Richardson, an assistant professor of physics and astronomy, has received a grant of $480,000 from the National Science Foundation to develop advanced instrumentation for the Laser Interferometer Gravitational-wave Observatory, or LIGO, based at sites in Louisiana and Washington. Completed in 2002, LIGO detects gravitational waves — ripples in space that travel at the speed...

How a supermassive black hole originates

Supermassive black holes, or SMBHs, are black holes with masses that are several million to billion times the mass of our sun. The Milky Way hosts an SMBH with mass a few million times the solar mass. Surprisingly, astrophysical observations show that SMBHs already existed when the universe was very young. For example, a billion...

Trions exhibit novel characteristics in moiré superlattices

When two similar atomic layers with mismatching lattice constants — the constant distance between a layer’s unit cells — and/or orientation are stacked together, the resulting bilayer can exhibit a moiré pattern and form a moiré superlattice. Moiré patterns are interference patterns that typically arise when one object with a repetitive pattern is placed over...

A new dimension in the quest to understand dark matter

As its name suggests, dark matter — material which makes up about 85% of the mass in the universe — emits no light, eluding easy detection. Its properties, too, remain fairly obscure. Now, a theoretical particle physicist at the University of California, Riverside, and colleagues have published a research paper in the Journal of High...

Veteran and community college transfer student heads to UCLA for graduate studies

When he joined the U.S. Navy in 2010, Mychal Valle didn’t think he would ever return to school. After all, he got to work on new radar technologies in the navy and got recognized for writing technical manuals. But by the time he left the navy in 2016, Valle’s service helped him discover his passion...

Researchers use a nanoscale synthetic antiferromagnet to toggle nonlinear spin dynamics

Researchers at the University of California, Riverside, have used a nanoscale synthetic antiferromagnet to control the interaction between magnons — research that could lead to faster and more energy-efficient computers. In ferromagnets, electron spins point in the same direction. To make future computer technologies faster and more energy-efficient, spintronics research employs spin dynamics — fluctuations...
