Electric field induced thermal Hall effect of triplons in the quantum dimer magnets $X$CuCl${}_3$ ($X=$ Tl, K)

Nanse Esaki, Yutaka Akagi, Hosho Katsura

We theoretically propose the electric field induced thermal Hall effect of triplons in the quantum dimer magnets $X$CuCl${}_3$ ($X=$ Tl, K), which exhibit ferroelectricity in the…
