Using an exact expression for the bi-spinor of parallel transport, we construct the Feynman propagator for Dirac fermions in the vacuum state on anti-de Sitter space-time. We compute the vacuum expectation value of the stress-energy tensor by removing coincidence-limit divergences using the Hadamard method. We then use the vacuum Feynman propagator to compute thermal expectation values at finite temperature. We end with a discussion of rigidly rotating thermal states.

    For a massless conformally coupled scalar field in rigidly rotating thermal states on AdS3 and AdS4, relativistic kinetic theory approximates the quantum stress-energy tensor well at high temperatures, and the quantum...
