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…

Phonons become chiral in the pseudogap phase of cuprates

G. Grissonnanche, S. Thériault, A. Gourgout +11

The nature of the pseudogap phase of cuprates remains a major puzzle. One of its new signatures is a large negative thermal Hall conductivity $κ_{xy}$ , which appears for doping…

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…
