Black hole thermodynamics

Classically, black hole thermodynamics is a formal analogy between black holes and statistical thermodynamics. Thermodynamic black holes have not just mass, charge and rotation, but also temperature and entropy. 41, May 2003 heat and mass seen above supports the assertion as well. We consider here one of Stephen Hawking's contributions to Physics. Dear Colleagues, In the four decades since its introduction into black hole physics, black hole entropy has proved a resilient and wide-ranging notion, with conceptual connections to a number of areas of the physical sciences, some far removed from black hole physics. It was originally put forth by Jacob Bekenstein in his landmark 1973 paper [1], in which he proposed treating black holes thermodynamically, and argued that the entropy should be proportional to the area of the event horizon. Black Hole Thermodynamics. A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. Some Simple Black Hole Thermodynamics Michael C. LoPresto, Henry Ford Community College, Dearborn, MI . The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. We consider here one of Stephen Hawking's contributions to Physics. Black Hole Thermodynamics, Hawking Radiation and Information Loss Paradox Alexander Vitanov Pro-Seminar in Theoretical Physics ETH Zurich Mai 11, 2009. Entropy, an international, peer-reviewed Open Access journal. I give a fairly systematic and thorough presentation of the case for regarding black holes as thermodynamic systems in the fullest sense, aimed at students and non-specialists and not presuming advanced knowledge of quantum … The boundary of the region from which no escape is possible is called the event horizon. 11.05.2009 Pro-Seminar, Prof. Renner Contents Introduction The classical laws of black hole mechanics Hawking radiation theory/GSL Microscopic description of black hole entropy Information loss paradox and possible solutions Summary . In ordinary thermodynamic systems, though, thermal properties appear as a consequence of statistical mechanics, that is, as a collective result of the behavior of large numbers of "microscopic" degrees of freedom. A reference is his famous book A Brief History of Time.Sadly, a former tutor in JPU200Y was completely correct when he proposed the following multiple choice question for a test: A reference is his famous book A Brief History of Time.Sadly, a former tutor in JPU200Y was completely correct when he proposed the following multiple choice question for a test: (a) black hole temperature: T H = hc 3 /16π 2 GkM The LHS is intensive but the RHS is not intensive; therefore a violation of thermodynamics [1,2]. 300 THE PHYSICS TEACHER Vol. I will then describe some of the remaining puzzles, including the nature of the quantum microstates, the problem of universality, and the information loss paradox. Black Hole Thermodynamics. The advantage of black hole thermodynamics is that provides a way to get a handle on the complex interactions black holes can have. Black hole thermodynamics and the Zeroth Law [1,2].
