Boulware state and semiclassical thermodynamics of black holes in a cavity
A black hole, surrounded by a reflecting shell, acts as an effective starlike object with respect to the outer region that leads to vacuum polarization outside, where the quantum fields are in the Boulware state. We find the quantum correction to the Hawking temperature, taking into account this circumstance. It …
