Abstract

The heavy-fermion superconductor URu₂Si₂ shows an intriguing increase of the thermal conductivity in the mixed-state immediately below the upper critical field H_c2 which is in a sharp contrast to common experience. A brief description of the origin of this behavior is given by focusing on the role of the semi-metallic Fermi surface reconstruction induced by the hidden order phase transition.
