Phys.org reports on the studies done by the Maryland Quantum Materials Center's researchers Dr. Johnpierre Paglione and Dr. Xiangfeng Wang. Researchers have demonstrated the first material that can have both strongly correlated electron interactions and topological properties. These materials create a playground for fundamental physics and are promising for a number of applications in special types of electronics and quantum computing.

A collaboration between QMC, NIST and the National High Magnetic Field Lab (NHMFL) has produced evidence for a rare phenomenon called re-entrant superconductivity in the material uranium ditelluride, a nearly ferromagnetic superconductor recently discovered in the Center. The team used the facilities of NHMFLto expose UTe2 samples to ultra-high magnetic fields as high as 65 Teslas as a function of field strength, angle orientation and temperature, uncovering yet another superconducting phase that is destroyed and then revived as a function of magnetic field. It was a record-busting performance for a superconductor and marked the first time two field-induced superconducting phases have been found in the same compound. The work is now published in Nature Physics, and reviewed here.
QMC is hosting a one-day symposium focusing on quantum materials research, bringing together researchers from the Departments of Physics, Chemistry and Biochemistry, Electrical and Computer Engineering, and Materials Science and Engineering at UMD, the National Institute of Standards and Technology (NIST) and the Laboratory for Physical Sciences.
The symposium is on Thursday, Sept. 26, 2019 at the University of Maryland in the Kim Engineering Building (see agenda here).
