# Local temperature in curved spacetime

@article{Buchholz2006LocalTI, title={Local temperature in curved spacetime}, author={Detlev Buchholz and Jan Schlemmer}, journal={Classical and Quantum Gravity}, year={2006}, volume={24}, pages={F25 - F31} }

A physically meaningful local concept of temperature is introduced in quantum field theory on curved spacetime and applied to the example of a massless field on de Sitter space. It turns out in this model that the equilibrium (Gibbs) states which can be prepared by a geodesic observer have in general a varying temperature distribution in the neighbourhood of the geodesic and may not even allow for a consistent thermal interpretation close to the horizon. This result, which can be traced back to…
