We compute the stress–energy operator for a scalar linear quantum field in curved space–time, modulo c–numbers. For the associated Hamiltonian operators, even those generating evolution along(More)
The prediction that black holes radiate due to quantum effects is often considered one of the most secure in quantum field theory in curved space–time. Yet this prediction rests on two dubious(More)
Black holes are extreme manifestations of general relativity, so one might hope that exotic quantum effects would be amplified in their vicinities, perhaps providing clues to quantum gravity. The(More)
