Imaginary part in thermo field dynamics

  • 1. Research Institute for Fundamental Physics, Kyoto University, Kyoto 606, Japan

Description

We investigate the imaginary part of Feynman diagrams in a real-time finite-temperature formalism, thermo field dynamics. Interesting relations are found which lead to a simple derivation of the imaginary part of self-energy diagrams
