Entropy of Schwarzschild black hole and string-black hole correspondence
نویسنده
چکیده
The string-black hole correspondence is considered in the context of the correspondence principle proposed recently by Horowitz and Polchinski [7]. We demonstrate that the entropy of string states and the entropy of a Schwarzschild black hole can be matched including the subleading terms which depend on mass logarithmically. We argue the necessity to include the string interaction (with coupling g) in the consideration and propose the g2-dependent modification of the string entropy. The matching of it with the entropy of Schwarzschild black hole is analyzed. PACS number(s): 04.70.Dy, 04.62.+v e-mail: [email protected]

Strings and black holes
I review some recent work (done in collaboration with G. Veneziano) which clarifies the existence of a correspondence between self-gravitating fundamental string states and Schwarzschild black holes. The main result is a detailed calculation showing that selfgravity causes a typical string state of mass M to shrink, as the string coupling g increases, down to a compact string state whose mass, ...
متن کاملThe entropy of black holes: a primer
After recalling the definition of black holes, and reviewing their energetics and their classical thermodynamics, one expounds the conjecture of Bekenstein, attributing an entropy to black holes, and the calculation by Hawking of the semi-classical radiation spectrum of a black hole, involving a thermal (Planckian) factor. One then discusses the attempts to interpret the black-hole entropy as t...
متن کاملA Correspondence Principle for Black Holes and Strings
For most black holes in string theory, the Schwarzschild radius in string units decreases as the string coupling is reduced. We formulate a correspondence principle, which states that (i) when the size of the horizon drops below the size of a string, the typical black hole state becomes a typical state of strings and D-branes with the same charges, and (ii) the mass does not change abruptly dur...
متن کاملCounting the Entropy of Schwarzschild Black Holes
A novel approach is described towards a microscopic understanding of the BekensteinHawking entropy of the simplest black hole – the Schwarzschild black hole. It is based at an intermediate step on the description of the black hole in terms of dual Euclidean brane/anti-brane pairs of type-IIB string-theory. By counting specific chain structures on the brane-complex one can reproduce the correct ...
متن کاملStatistical Entropy of Schwarzschild Black Strings and Black Holes
The statistical entropy of a Schwarzschild black string in five dimensions is obtained by counting the black string states which form a representation of the near-horizon conformal symmetry with a central charge. The statistical entropy of the string agrees with its Bekenstein-Hawking entropy as well as that of the Schwarzschild black hole in four dimensions. The choice of the string length whi...
