Thermal-Hall conductivity and long-lived quasiparticles in CeCoIn

arXiv:cond-mat/0610713 · doi:10.1016/j.physc.2007.03.080

Abstract

In CeCoIn, the thermal conductivity and Hall conductivity below display large anomalies below . 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.
