Thermal conductivity and competing orders in d-wave superconductors

Abstract

We derive the expression for the thermal conductivity κin the low-temperature limit T \to 0 in d-wave superconductors, taking into account the presence of competing orders such as spin-density wave, is-pairing, etc.. The expression is used for analyzing recent experimental data in La_{2-x}Sr_xCuO_4. Our analysis strongly suggests that competing orders can be responsible for anomalies in behavior of thermal conductivity observed in those experiments.
