The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; show every role.

We generalize the discussion of hep-th/0509170 to charged black holes. For the two dimensional charged black hole, which is described by an exactly solvable worldsheet theory, a transition from the black hole to the string phase occurs when the Hawking temperature of the black hole reaches a limiting value, the temperature of free strings with the same mass and charge. At this point a tachyon winding around Euclidean time in the Euclidean black hole geometry, which has a non-zero condensate, becomes massless at infinity, and the horizon of the black hole is infinitely smeared. For Reissner-Nordstrom black holes in d\ge 4 dimensions, the exact worldsheet CFT is not known, but we propose that it has similar properties. We check that the leading order solution is in good agreement with this proposal, and discuss the expected form of \alpha' corrections.

The paper

Original abstract

We generalize the discussion of hep-th/0509170 to charged black holes. For the two dimensional charged black hole, which is described by an exactly solvable worldsheet theory, a transition from the black hole to the string phase occurs when the Hawking temperature of the black hole reaches a limiting value, the temperature of free strings with the same mass and charge. At this point a tachyon winding around Euclidean time in the Euclidean black hole geometry, which has a non-zero condensate, becomes massless at infinity, and the horizon of the black hole is infinitely smeared. For Reissner-Nordstrom black holes in d\ge 4 dimensions, the exact worldsheet CFT is not known, but we propose that it has similar properties. We check that the leading order solution is in good agreement with this proposal, and discuss the expected form of \alpha' corrections.

Two towers of discrete worldsheet states in the (SL(2,R) x U(1))/U(1) coset produce the Schwarzian (3/2)log T correction near extremality of the charged 2D black hole, and the modular-integral evaluation recovers the ...

String star phase diagrams on a spatial circle are computed: new d=2 solutions, a quartic-induced d=5 swallowtail, and an anomalous d=6 stability pattern.
Matrix models for D-particle dynamics and the string/black hole transition
hep-th 2006-03 conditional novelty 6.0 of 10

Using a canonical transformation, D0-brane dynamics in 2D 0A string backgrounds are mapped to matrix models; at the Hagedorn temperature the black hole matrix model exactly matches the linear dilaton matrix model.

In the near-horizon geometry of the coincident fivebranes, the three-charge black holes are described by certain BPS black hole solutions in an asymptotically linear dilaton spacetime, which carry the charges $(P,W)$; see e.g. [ref] and references therein.
