Abstract
We show that the appropriate vacuum state for the interior of a box with reflecting walls being lowered adiabatically toward a Schwarzschild black hole is the Boulware state. This is concordant with the results of Unruh and Wald, who used a different approach to obtain the stress-energy inside the box, but does not agree with Li and Liu, who only consider the quantum state outside of the box.Keywords
