Aspects of the black hole/string transition
Yiming Chen, Princeton University
Event Type: HEP Seminar
Time: 02:00 PM - 03:00 PM
Location: 726 Broadway, 940, CCPP Seminar
Abstract: It has long been speculated that a black hole in string theory turns into highly excited strings close to the Hagedorn temperature. Gravitational attraction pulls different parts of the string together, forming a star-like configuration. In this talk, I will review the properties of a concrete solution of this kind, first discovered by Horowitz and Polchinski. I will discuss whether the Horowitz-Polchinski solution can be smoothly connected with the black hole as worldsheet CFTs. I will also discuss how the story can be generalized to charged cases, as well as its implication on the near extremal limit.
