Back reaction effects in black hole spacetimes

We solve the semiclassical Einstein equations for the static spherically symmetric case. Using expressions for the renormalized 〈Tμv〉, we study the effects of the back reaction on black hole spacetimes at the one-loop level. Two different situtaions appear depending on the graviton-matter balance. I...
