Thermal transport in the hidden-order state of URu${}_2$Si${}_2$

Abstract

We present a study of thermal conductivity in the normal state of the heavy-fermion superconductor URu${}_2$Si${}_2$. Ordering at 18K leads to a steep increase in thermal conductivity and (in contrast with all other cases of magnetic ordering in heavy-fermion compounds) to an enhancement of the Lorenz number. By linking this observation to several other previously reported features, we conclude that most of the carriers disappear in the ordered state and this leads to a drastic increase in both phononic and electronic mean-free-path.
