Title: An angle resolved low temperature thermal conductivity study on Csv3Sb5
Abstract: Low temperature angle resolved thermal conductivity measurements are useful for probing anisotropies and low energy excitation symmetries as well as identifying nodal structures of unconventional superconductors energy gaps. This talk will mainly revolve around the setup and method involved in these studies as well as how to interpret results from these measurements. In particular, I will be presenting our findings using this method on the Kagome lattice superconductor CsV3Sb5, a material known for its time reversal symmetry breaking charge order state that competes with its superconducting ground state. Our thermal transport results preliminarily show a time reversal symmetry breaking in the superconducting state as well as a validation of its hexagonal symmetry.
