Description

We study the invariance of thermo field dynamics (TFD) for equilibrium systems under local gauge transformations. We show that when restricted to a conveniently constrained subspace of thermal states, TFD has the structure of a gauge theory, the gauge vector field playing the role of the reservoir response to the system dynamics.
