The vacuum expectation value of the stress-energy tensor ã€ˆ0 |TÎ¼Î½ | 0ã€‰ is calculated in several multiply connected flat spacetimes for a massive scalar field with arbitrary curvature coupling. We findâ€¦ (More)

The stress-energy tensor of a free quantized scalar field is calculated in the extreme Reissner-NordstrÃ¶m black hole spacetime in the zero temperature vacuum state. The stress-energy appears to beâ€¦ (More)
