CAPST researchers Wave Ngampruetikorn and James Sauls published new theoretical predictions of a Zero-Field Thermal Hall Effect as a signature of a broken P and T ground state in Topological Superconductors

Chiral superconductors exhibit novel transport properties that depend on the topology of the order parameter, topology of the Fermi surface, the spectrum of bulk and edge Fermionic excitations, and the structure of the impurity potential. In the case of electronic...

Broken time-reversal symmetry in the topological superconductor UPt3

CAPST researchers in Physics, Keenan Avers, William Halperin, and James Sauls, in collaboration with the neutron scattering team led by Morten Eskildsen at Notre Dame, report the discovery of Broken time-reversal symmetry in the topological superconductor UPt3:...

New Quantum Phases of Matter Confined in Quantized Vortices

Classical liquids achieve co-rotation in a rotating container through the force of the walls on the fluid and viscous forces in the fluid. Quantum liquids, like Helium, are fundamentally different. They obey the laws of quantum mechanics in aggregate, with the...
