Non - extremal fractional branes †
We construct non-extremal fractional D-brane solutions of type-II string theory at the Z 2 orbifold point of K3. These solutions generalize known extremal fractional-brane solutions and provide further insights into N = 2 supersymmetric gauge theories and dual descriptions thereof. In particular, we find that for these solutions the horizon radius cannot exceed the non-extremal enhançon radius....
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 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 کاملLocalized Intersections of Non-Extremal p-branes and S-branes
A class of solutions to Supergravity in 10 or 11 dimensions is presented which extends the non-standard or semi-local intersections of Dp-branes to the case of non-extremal p-branes. The type of non-extremal solutions involved in the intersection is free and we provide two examples involving black-branes and/or D−D̄ systems. After a rotation among the time coordinate and a relatively transverse ...
متن کاملNear-Extremal Black Hole Entropy and Fluctuating 3-Branes
We discuss the known microscopic interpretations of the Bekenstein-Hawking entropy for configurations of intersecting M-branes. In some cases the entropy scales as that of a massless field theory on the intersection. A different situation, found for configurations which reduce to 1-charge D = 5 black holes or 2-charge D = 4 black holes, is explained by a gas of non-critical strings at their Hag...
