C7 – Thermodynamics of quantum fields in non-stationary spacetimes
The principles of thermodynamics are based on a time independent dynamics. To arrive at a local thermodynamic interpretation of a state on a generic spacetime one compares expectation values of fields with those in homogeneous equilibrium states on Minkowski space. In this way local thermodynamical terms can be introduced. These quantities shall be investigated in perturbatively constructed models. The aim is a deeper understanding of thermodynamical aspects of cosmology.
