Thermal Fields, Entropy, and Black Holes
In this review we describe statistical mechanics of quantum systems in the presence of a Killing horizon and compare statistical-mechanical and one-loop contributions to black hole entropy. Studying these questions was motivated by attempts to explain the entropy of black holes as a statistical-mechanical entropy of quantum fields propagating near the black hole horizon. We provide an introduct...
متن کاملBlack Holes, Entropy, and Information
Black holes are a continuing source of mystery. Although their classical properties have been understood since the 1970’s, their quantum properties raise some of the deepest questions in theoretical physics. Some of these questions have recently been answered using string theory. I will review these fundamental questions, and the aspects of string theory needed to answer them. I will then expla...
متن کاملEvaporating black holes and entropy.
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...
متن کاملBlack Holes, Thermodynamics and Entropy
Black holes, thermodynamics and entropy are three topics which both separately and together raise several quite deep and serious questions which need to be addressed. Here an attempt is made to highlight some of these issues and to indicate a possible linkage between the accepted entropy expression for a black hole and the paradox linked to black holes and information loss.
متن کاملThermal BEC Black Holes
We review some features of Bose–Einstein condensate (BEC) models of black holes obtained by means of the horizon wave function formalism. We consider the Klein–Gordon equation for a toy graviton field coupled to a static matter current in a spherically-symmetric setup. The classical field reproduces the Newtonian potential generated by the matter source, while the corresponding quantum state is...
