Low Temperature Thermal Transport in RuCl3

ORAL

Abstract

RuCl3 is currently the primary material candidate for realizing the Kitaev Honeycomb model and its exotic Majorana fermion excitations. We have measured the longitudinal and Hall thermal conductivity of RuCl3 down to He3 temperatures (0.3 K). The longitudinal thermal conductivity displays periodic oscillations that may be indicative of Landau quantization. We also observe a thermal Hall conductivity similar to that observed by Kasahara et al. [1] and will provide updates on our attempts to verify the quantization.
