Description
I review the approaches to descriptions of thermal equilibrium states in both quantum mechanics and quantum field theory. I argue, that the description via (Gibbs) density functionals is not sufficient to describe thermal equilibrium states in generic situations. I show a generalization of Gibbs states, the so-called KMS-states, and their application to quantum field theory.
