概要

• 論文の詳細を見る

• Formalism of thermo field dynamics in classical mechanics with constraints, which is a natural consequence of the time-dependent Hartree-Fock theory for mixed states, is reformulated under the introduction of a gauge fixing condition. With the aid of this condition, the formulation is performed in the frame of Dirac's canonical theory with constraints. Any physical quantity can be expressed in terms of constraint-independent canonical variables.
