Spin the spin liquid cadidate α-RuCl₃

α-RuCl₃ continues to attract significant research interests due to its potential for realizing Kitaev spin liquid states. Thermal transport studies on α-RuCl₃ have revealed exciting phenomena from oscillations to quantization. In this presentation, we will explore these phenomena from a different angle and at a different length scale. By spinning the (putative) spin liquid with respect to the external magnetic field, we can infer rotaional symmetry of its ordered and disordered ground states. For fields within the ab-plane, we observe a distinct symmetry reduction associated with the spin-disordered state. Additionally, the thermal Hall effect is shown to be nonvanishing only in the field and angle range where thermal conductivity still oscillates – a correlation which eluded prior investigations. For fields in the ac-plane, the oscillation period scales with the square root of the total field strength, while its amplitude scales with the cubic power. Lastly, I will discuss our recent efforts to mitigate the unwelcome effects of bulk phonons by reducing the transport region's dimension to approach the mesoscopic limits.
