Description
The Bloch-Messiah theorem is extended to the thermal Hartree-Fock-Bogoliubov (THFB) theory by making use of the thermo field dynamics. This enables us to define the correct order parameter describing superconducting phase at finite temperature, and demonstrates consistency of the THFB formalism. (orig.)
