Microscopic Connection between Phonon Hall Viscosity and Acoustic Faraday Effect in Spin-Orbit-Coupled Magnets
Antoine Matar, Haoting Xu, Hae-Young Kee
The acoustic Faraday effect probes phonon Hall viscosity through the rotation of transverse acoustic polarization, conventionally interpreted in terms of circular birefringence. We…

Understanding Anomalous Magnetothermal Transport via Disentangling Shear and Compression Phonons
Haoting Xu, Antoine Matar, Hae-Young Kee
Magnetothermal transport in various frustrated magnets exhibits striking field-dependent anomalies that deviate from conventional magnon or phonon transport. To understand such ano…
