Annihilation operators associated with unstable vacua in non-equilibrium thermo-field dynamics
Out of thermal equilibrium state, the vacuum is unstable and evolves in time. Consequently, the annihilation operators associated with the unstable vacuum depend on time. This dissipative time-evolution of quantum systems can be systematically treated, within the canonical operator formalism refer...
