Competing Energy Scales and Phase Separation in Topological Superconductor Sn_0.4Sb_0.6 Alloys: Temperature- and Excitation-Dependent Ultrafast Pump–Probe Studies

Abstract

This article builds upon our previous research on Sn 0.4 Sb 0.6 topological superconductor alloys, with a specific focus on the charge carrier dynamics and their spectral responses under varying conditions. In our prior work, we investigated the superconducting properties and fluence-dependent charge carrier dynamics of Sn 0.4 Sb 0.6 , highlighting its bulk type-II superconductivity, band filling, and photobleaching phenomenon Sharma, M.
