Abstract

We derive the Bekenstein-Hawking entropy formula for four and five dimensional non-supersymmetric black holes (which include the Schwarzchild ones) by counting microscopic states. This is achieved by first showing that these black holes are U-dual to the three-dimensional black hole of Banados-Teitelboim-Zanelli and then counting microscopic states of the latter following Carlip's approach. Higher than five dimensional black holes are also considered. We discuss the connection of our approach to the D-brane picture.

Vacuum interpolation in supergravity via super p-branes

G. Gibbons, P. Townsend (1993)

We show that many of the recently proposed supersymmetric p-brane solutions of d=10 and d=11 supergravity have the property that they interpolate between Minkowski spacetime and a compactified spacetime, both being supersymmetric supergravity vacua. Our results imply that the effective worldvolume action for small fluctuations of the super p-brane is a supersingleton field theory for \((adS)_{p+2}\), as has been often conjectured in the past.

On the Nonperturbative Consistency of \(d=2\) String Theory

Joseph Polchinski (1994)

An infinite number of distinct \(d=1\) matrix models reproduce the perturbation theory of \(d=2\) string theory. Due to constraints of causality, however, we argue that none of the existing constructions gives a consistent nonperturbative definition of the \(d=2\) string.

A Correspondence Principle for Black Holes and Strings

Gary T. Horowitz, Joseph Polchinski (1996)

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 during the transition. This provides a statistical interpretation of black hole entropy. This approach does not yield the numerical coefficient, but gives the correct dependence on mass and charge in a wide range of cases, including neutral black holes.
