Researchers devise tunable conducting edge

A research team led by a physicist at the University of California, Riverside, has demonstrated a new magnetized state in a monolayer of tungsten ditelluride, or WTe2, a new quantum material. Called a magnetized or ferromagnetic quantum spin Hall insulator, this material of one-atom thickness has an insulating interior but a conducting edge, which has...

Why are dark matter halos of ultra-diffuse galaxies so … odd?

A study co-led by physicists at UC Riverside and UC Irvine has found that dark matter halos of ultra-diffuse galaxies are very odd, raising questions about physicists’ understanding of galaxy formation and the structure of the universe. Ultra-diffuse galaxies are so called because of their extremely low luminosity. The distribution of baryons — gas and...

Unraveling a mystery surrounding cosmic matter

Early in its history, shortly after the Big Bang, the universe was filled with equal amounts of matter and “antimatter” — particles that are matter counterparts but with opposite charge. But then, as space expanded, the universe cooled. Today’s universe is full of galaxies and stars which are made of matter. Where did the antimatter...

Two New Faculty Positions in Experimental Cosmology, Particle Astrophysics, and Gravitational Waves

The Physics and Astronomy Department is adding two more faculty positions to the growing Experimental Cosmology, Particle Astrophysics, and Gravitational Waves research group.

A summer of particle physics

Three young physicists at the University of California, Riverside, have been thinking big. Gigantic-particle-accelerator big. Undergraduates Andrew Caruso, Robert Vasquez, and Selim Zoorob did internships this summer at the European Organization for Nuclear Research, or CERN. The center is home to the Large Hadron Collider, or LHC, the world’s largest and most powerful particle accelerator.
Rodolfo Rodriquez is PhD student in Prof. Barsukov's group and the lead author of the study.

Antiferromagnetic hybrids achieve important functionality for spintronic applications

Antiferromagnets have zero net magnetization and are insensitive to external magnetic field perturbations. Antiferromagnetic spintronic devices hold great promise for creating future ultra-fast and energy-efficient information storage, processing, and transmission platforms, potentially leading to faster and more energy-efficient computers.

Major conference on magnetism in Southern California

Excitations in magnets -- magnons -- hold great promise for quantum and classical information processing due to excellent scalability, tunability and energy-efficiency of magnonic devices. Magnonics is at the forefront of fundamental and applied research in magnetism and attracts excellent scientists all over the world. This year, the seventh in the series of the renowned...

Transfer student wins award at his first conference

An undergraduate student at UC Riverside won an award at the very first scientific conference he attended.

Researchers report discovery of novel electronic state

In a paper published earlier this month in Nature Physics, Yongtao Cui, an associate professor of physics and astronomy at UC Riverside, and colleagues report the discovery of a novel electronic state in a new type of moiré superlattice formed by 2D materials.

Physicist receives lifetime award from American Physical Society

UC Riverside physicist Simeon Bird is among the 146 Outstanding Referees for 2022, as chosen by the APS.

How a virus packages its genetic material

Each simple RNA virus has a genome, its “native RNA.” This genome dictates how the virus replicates in cells to eventually cause disease. The genome also has the code for making a capsid, the protein shell of a virus that encapsulates the genome and protects it like a nanocontainer. A team led by Roya Zandi...

Physics undergraduate accepted into prestigious summer research program at Caltech

Peter Carney, a second-year undergraduate student at UC Riverside, has earned a spot in a prestigious and highly competitive summer undergraduate research fellowship program at the California Institute of Technology in Pasadena. The program is hosted by Caltech LIGO. LIGO, which stands for Laser Interferometer Gravitational-wave Observatory, is based at sites in Louisiana and Washington...

Surprisingly high fraction of dead galaxies found in ancient galactic city

n international team of astronomers led by researchers at the University of California, Riverside, has discovered an unusual massive cluster of young galaxies forming in the early universe. The newly discovered growing galactic metropolis, named MAGAZ3NE J095924+022537, is a newborn galaxy cluster, or protocluster, consisting of at least 38 member galaxies, and is about 11.8...

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...

Department of Energy renews quantum condensed matter grant to physicist

The Basic Energy Sciences program of the U.S. Department of Energy has renewed a grant to Michael Mulligan, an assistant professor of physics and astronomy. The three-year grant of $370,000 will support research by Mulligan and UCR graduate students in quantum condensed matter theory. The Basic Energy Sciences program supports basic scientific research to lay...

Grant to physicists will help design nuclear physics detector with artificial intelligence

UC Riverside is the lead institution of a grant from the Department of Energy, or DOE, to use machine learning techniques to optimize the design of the ATHENA detector, one of the proposed experiments for the future Electron-Ion Collider, or EIC. The research team, which includes members from the Lawrence Livermore National Laboratory and Lawrence...

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...
