Invited Talk Unconventional Superconductors and Intertwined Phases

Speaker

Prof. Srinivas Raghu (Stanford University)

Description

UTe${}_2$ exhibits a variety of intriguing properties including field-induced reentrance of superconductivity. In the first part of the talk, we will suggest that the reentrance can be accounted for by invoking multiple superconducting phases, for which there is considerable recent experimental evidence. In the second part of the talk, we will describe candidate superconducting order parameters for these various superconducting phases, in the context of a microscopic model having the same symmetries as UTe${}_2$.
