Abstract
We introduce a new state representation \eta] for thermal field dynami cs, which possesses orthonormal and completeness relations. The therma l operator, which engenders the transition from zero temperature to fi nite temperature, is shown to have a natural representation in the rep resentation manifestly exhibiting squeezing. The relationship between temperature evolution dynamics and the squeezing is also discussed. (C ) 1998 Elsevier Science B.V.
