Thermal-Hall conductivity and long-lived quasiparticles in CeCoIn$_5$
  In CeCoIn$_5$, the thermal conductivity $\kappa_{xx}$ and Hall conductivity $\kappa_{xy}$ 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.
