  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.
