Thermal Transport Probe to the Quantum Spin Liquid State of α-RuCl₃

Thermal transport measurements offer a powerful approach to probing the exotic physics of quantum materials. In the candidate Kitaev spin liquid α-RuCl₃, such measurements have uncovered intriguing phenomena. Notably, the oscillatory behavior of thermal conductivity and the half-integer quantized planar thermal Hall effect have captured significant attention in the research community. Despite these fascinating findings, their underlying nature remains a topic of intense debate. In this presentation, I will discuss the field-angle-dependent thermal transport properties of α-RuCl₃, highlighting the observed symmetry breaking in the field-induced quantum spin liquid state and the correlation between oscillatory thermal conductivity and plateau-like features in the thermal Hall conductivity.
