Abstract

In CeCoIn₅, the thermal conductivity κ_xx and Hall conductivity κ_xy below T_c display large anomalies below T_c. 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.
