Zusammenfassung:
We apply the formalism of thermofield dynamics to group field theory quantum
gravity and construct thermal representations associated with generalised
equilibrium Gibbs states using Bogoliubov transformations. The newly
constructed class of thermal vacua are entangled, two-mode squeezed,
thermofield double states. The corresponding finite temperature representations
are inequivalent to the standard zero temperature one based on a degenerate
vacuum. An interesting class of states, coherent thermal states, are defined
and understood as thermal quantum gravity condensates.
