摘要
We study the Hawking radiation for the geometry of an evaporating (1 + 1)-dimensional black hole. We compute Bogoliubov coefficients and the stress tensor. We use a recent result of Srednicki to estimate the entropy of entanglement produced in the evaporation process, for the (1 + 1)-dimensional hole and for the (3 + 1)-dimensional hole. It is found that the one-space-dimensional result of Srednicki is the pertinent one to use, in both cases.
