Relative entropy formulation of thermalization process in a Schwarzschild spacetime by Si-Wei Han, Zhichun Ouyang, Zhiyao Hu, Jun Feng

“…Finally, from a perspective of quantum thermodynamics, we recast the free energy change of the UDW detector undergoing Hawking radiation into an entropic combination form, where the classical Kullback-Leibler divergence and quantum coherence are presented in specific QRE-like forms. …”

Dark Matter and Dark Energy Induced by Condensates by Antonio Capolupo

“…It is shown that the thermal states with the cosmic microwave radiation temperature and the Unruh and the Hawking radiations give negligible contributions to the critical energy density of the universe, while the thermal vacuum of the intercluster medium could contribute to the dark matter, together with the vacuum energy of fields in curved space-time and of mixed neutrinos. …”
