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.
