Abstract

In CeCoIn5, the thermal conductivity κxx and Hall conductivity κxy below Tc display large anomalies below Tc. The strong suppression of the anomalies in weak fields implies the existence of long-lived quasiparticles. We also discuss briefly the Wiedemann-Franz ratio and the existence of a strongly field-dependent spin-fluctuation heat current.
