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.
Condensed Matter Physics
What is Condensed Matter Physics?
Condensed matter physics attempts to understand and manipulate the properties of matter in its solid and liquid forms from fundamental physical principles of quantum and statistical mechanics.
What are we doing in Condensed Matter Physics at Illinois?
The University of Illinois maintains a distinguished tradition of focusing on the collective properties of matter and the emergence of novel and unusual states of matter, such as superconductivity and superfluidity.
Research in these areas has been recognized by numerous major awards, including Nobel Prizes to John Bardeen and Anthony Leggett. However, the university is also distinguished by its strong contributions to the development of technology emanating from condensed matter physics, especially in the area of semiconductor physics.
Today, the condensed matter group is the largest focus area in the department, with vibrant programs in both theory and experimental work. Every area of modern-day condensed matter physics is represented at Illinois, together with numerous cross-disciplinary programs in atomic, molecular and optical physics, materials science, and even biology.
