What is Quantum Source of Entropy for Black Holes about?

%e associate to any quantum field propagating in the background metric of a black hole an effec- tive density matrix whose statistical entropy can be interpreted as a contribution to the total entropy of the black hole. By evaluating this contribution in a simplified case, we show that in general it can be expected to be finite and proportional to the area of the black hole. As a by-product of our calcu- lation we obtain a general expression for the entropy of any real Gaussian density matrix. ' 1/2 m(ly ) 1 +y2 y (x+x'} exp (1y )(1+y )
