Abstract

In this work we deene a new state on the Weyl algebra of the free massive scalar Klein-Gordon eld on a Robertson-Walker spacetime and prove that it is a Hadamard state. The state is supposed to approximate a thermal equilibrium state on a Robertson-Walker spacetime and we call it an adiabatic KMS state. This opens the possibility to do quantum statistical… (More)
