Planar thermal Hall effect from phonons in a Kitaev candidate material

Lu Chen, Étienne Lefrançois, Ashvini Vallipuram +5

Kitaev materials are a promising platform for the realization of quantum spin liquid states. The thermal Hall effect has emerged as a potential probe of exotic excitations within s…

Thermal Hall conductivity in the cuprate Mott insulators Nd $_{2}$ CuO $_{4}$ and Sr $_{2}$ CuO $_{2}$ Cl $_{2}$

Marie-Eve Boulanger, Gaël Grissonnanche, Sven Badoux +11

The heat carriers responsible for the unexpectedly large thermal Hall conductivity of the cuprate Mott insulator La $_{2}$ CuO $_{4}$ were recently shown to be phonons. However, the mecha…

Thermal conductivity of the quantum spin liquid candidate EtMe3Sb[Pd(dmit)2]2: No evidence of mobile gapless excitations

P. Bourgeois-Hope, F. Laliberté, E. Lefrançois +9

The thermal conductivity $κ$ of the quasi-2D organic spin-liquid candidate EtMe $_{3}$ Sb[Pd(dmit) $_{2}$ ] $_{2}$ (dmit-131) was measured at low temperatures, down to 0.07 K. We observe a va…
