| Abstract: | We derive the expression for the thermal conductivity  in the low-temperature limit  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  . Our analysis strongly suggests that competing orders can be responsible for anomalies in behavior of thermal conductivity observed in those experiments.Received: 9 December 2003, Published online: 2 April 2004PACS: 74.25.Fy Transport properties (electric and thermal conductivity, thermoelectric effects, etc.) - 74.72.Dn La-based cuprates - 74.72.-h Cuprate superconductors (high-Tc and insulating parent compounds)V.P.
