摘要
En 中文
A D4-D0 black hole can be deconstructed into a bound state of D0 branes with a D6-(D) over bar6 pair containing worldvolume fluxes. The exactha spacetime solution is known and resembles a D0 accretion disk surrounding a D6-(D) over bar6 core. We find a scaling limit in which the disk and core drop inside an AdS(2) throat. Crossing this AdS(2) throat and the D0 accretion disk into the core, we find a second scaling region describing the D6-D6 pair. It is shown that the M-theory lift of this region is AdS(3) x S-2. Surprisingly, time translations in the far asymptotic region reduce to global, rather than Poincare, time translations in this core AdS(3). We further find that the quantum mechanical ground state degeneracy reproduces the Bekenstein-Hawking entropy-area law.
