• Research Funding

The Gordon and Betty Moore Foundation, through its Emergent Phenomena in Quantum Systems Initiative (EPiQS), has awarded substantial research funding to two experimental condensed matter physicists at the University of Illinois at Urbana-Champaign. Physics Professors Peter Abbamonte and Vidya Madhavan will receive EPiQS Experimental Investigator awards of $1.6 million each over the next five years.

EPiQS prioritizes high-risk, high-reward fundamental research programs in quantum materials, to foster scientific breakthroughs. EPiQS experimental investigators have the freedom to pursue challenging and novel research directions of the scientists’ own choosing.

Particle chasing—it’s a game that so many physicists play. Sometimes the hunt takes place inside large supercolliders, where spectacular collisions are necessary to find hidden particles and new physics. For physicists studying solids, the game occurs in a much different environment and the sought-after particles don’t come from furious collisions. Instead, particle-like entities, called quasiparticles, emerge from complicated electronic interactions that happen deep within a material. Sometimes the quasiparticles are easy to probe, but others are more difficult to spot, lurking just out of reach.

Now a team of researchers at the University of Illinois, led by physicist Vidya Madhavan, in collaboration with researchers from the National Institute of Standards and Technology, the University of Maryland, Boston College, and ETH Zurich, have used high-resolution microscopy tools to peer at the inner-workings of an unusual type of superconductor, uranium ditelluride (UTe2). Their measurements reveal strong evidence that this material may be a natural home to an exotic quasiparticle that’s been hiding from physicists for decades. The study is published in the March 26 issue of Nature.

Since the discovery two decades ago of the unconventional topological superconductor Sr2RuO4, scientists have extensively investigated its properties at temperatures below its 1 K critical temperature (Tc), at which a phase transition from a metal to a superconducting state occurs. Now experiments done at the University of Illinois at Urbana-Champaign in the Madhavan and Abbamonte laboratories, in collaboration with researchers at six institutions in the U.S., Canada, United Kingdom, and Japan, have shed new light on the electronic properties of this material at temperatures 4 K above Tc. The team’s findings may elucidate yet-unresolved questions about Sr2RuO4’s emergent properties in the superconducting state.

  • Accolades

Three Physics Illinois faculty members—Professors Matthias Grosse Perdekamp, Vidya Madhavan, and Brian DeMarco—have been elected Fellows of the American Physical Society. Election to Fellowship is a distinct honor that recognizes significant contributions to the field, including outstanding physics research, important applications of physics, leadership in or service to physics, or significant contributions to physics education.
