Pair-Breaking Study of High-Spin Topological Superconductor YPtBi

ORAL

Abstract

YPtBi has been a promising candidate for exploring the interplay of topological band structure and superconductivity. With a superconducting transition at 0.7 K, the extremely low carrier density semimetal YPtBi hosts an extremely unusual superconducting state with posited high-spin (j=3/2) pairing states that explain a nodal order parameter structure. Here we describe experiments to probe the pair-breaking effect on superconductivity in YPtBi as a function of controlled disorder in order to gain insight into the nature of the superconducting state.
