/ 9710014 Semiclassical Decay of near - Extremal Fivebranes
We argue that a near-extremal charge-k type II NS fivebrane can be reliably described in semiclassical string perturbation theory as long as both k and µ k are large, where µ is the energy density in string units. For a small value of the asymptotic string coupling g, the dynamics in the throat surrounding the fivebrane reduces to the CGHS model with massive fields. We find that the energy dens...
متن کاملStatistical Entropy of Near Extremal Five-Branes
The Hawking Beckenstein entropy of near extremal fivebranes is calculated in terms of a gas of strings living on the fivebrane. These fivebranes can also be viewed as near extremal black holes in five dimensions. 1 e-mail: [email protected] Recently the Bekenstein-Hawking entropy of certain extremal BPS black holes was precisely calculated by counting microstates in string theory [1-4]...
متن کاملEntropy of near-extremal dyonic black holes
In this note it is shown that near-extremal four dimensional dyonic black holes, where the dilaton is not constant, can be described by a microscopic model consisting of a one-dimensional gas of massless particles.
متن کاملEntropy of Near-Extremal Black p-branes
We carry out a thorough survey of entropy for a large class of p-branes in various dimensions. We find that the Bekenstein-Hawking entropy may be given a simple world volume interpretation only for the non-dilatonic p-branes, those with the dilaton constant throughout spacetime. The entropy of extremal non-dilatonic p-branes is non-vanishing only for solutions preserving 1/8 of the original sup...
متن کاملEntropy of near-extremal black holes in AdS5
We construct the microstates of near-extremal black holes in AdS5 × S5 as gases of defects distributed in heavy BPS operators in the dual SU(N) Yang–Mills theory. These defects describe open strings on spherical D3-branes in the S5, and we show that they dominate the entropy by directly enumerating them and comparing the results with a partition sum calculation. We display new decoupling limits...
