D-brane configuration and black hole thermodynamics
نویسنده
چکیده
We consider a configuration of strings and solitons in the type IIB superstring theory on M5 × T 5, which is composed of a set of arbitrarily-wound D-fivebranes on T 5 and a set of arbitrarily-wound D-strings on S1 of the torus. For the configuration, it is shown that number of microscopic states is upper-bounded by the exponential of Hawking-Bekenstein entropy of the corresponding black hole and temperature of closed string radiation from the D-branes is lower-bounded by Hawking temperature of the black hole. After discussing the necessary and sufficient condition to saturate these bounds, we give some speculations about black hole thermodynamics.

Black Holes and Instabilities of Negative Tension Branes
We consider the collision in 2+1 dimensions of a black hole and a negative tension brane on an orbifold. Because there is no gravitational radiation in 2+1 dimensions, the horizon area shrinks when part of the brane falls through. This provides a potential violation of the generalized second law of thermodynamics. However, tracing the details of the dynamical evolution one finds that it does no...
متن کاملWarped brane - world compactification , black hole thermodynamics and holographic cosmology with R 2 terms
We present a linear treatment of the Einstein-Gauss-Bonnet gravity on a singular co-dimension one brane embedded in (d + 1) dimension anti-de Sitter spacetimes. We exhibit that the zero-energy solution corresponds to the localized massless graviton on the brane with correct momentum and tensor structures. By introducing the higher curvature terms in quadratic form, we consider a braneuniverse i...

متن کاملU duality, D-branes, and black hole emission rates: Agreements and disagreements
An expression for the spacetime absorption coefficient of a scalar field in a five dimensional, near extremal black hole background is derived, which has the same form as that presented by Maldacena and Strominger, but is valid over a larger, U-duality invariant region of parameter space and in general disagrees with the corresponding D-brane result. We develop an argument, based on D-brane the...
متن کاملThermodynamics of D-brane Probes
We discuss the dynamics and thermodynamics of particle and D-brane probes moving in non-extremal black hole/brane backgrounds. When a probe falls from asymptotic infinity to the horizon, it transforms its potential energy into heat, TdS, which is absorbed by the black hole in a way consistent with the first law of thermodynamics. We show that the same remains true in the near-horizon limit, for...
