Self Gravitating Spinning String Condensates
Jorge E. Santos, Yoav Zigdon
In the context of the black hole/string transition, it is useful to produce Euclidean string backgrounds representing hot and self-gravitating strings. We utilise analytical and nu…
BPS Fivebrane Stars II: Fluctuations
Emil J. Martinec, Yoav Zigdon
We investigate quantum fluctuations of metric components in coherent 1/2-BPS bound states of fundamental strings and NS5-branes. The leading order contribution in an ex…
BPS Fivebrane Stars I: Expectation Values of Observables
Emil J. Martinec, Yoav Zigdon
We study ensembles of 1/2-BPS bound states of fundamental strings and NS-fivebranes (NS5-F1 states) in the AdS decoupling limit. We revisit a solution corresponding to an ensemble…
On the Entropy of Strings and Branes
Ram Brustein, Yoav Zigdon
We show that the entropy of strings that wind around the Euclidean time circle is proportional to the Noether charge associated with translations along the T-dual time direction. W…
Thermal Equilibrium in String Theory in the Hagedorn Phase
Ram Brustein, Yoav Zigdon
In string theory, a thermal state is described by compactifying Euclidean time on a thermal circle , of fixed circumference. However, this circumference is a dynamical fie…
A Puncture in the Euclidean Black Hole
Ram Brustein, Amit Giveon, Nissan Itzhaki +1
We consider the backreaction of the winding condensate on the cigar background. We focus on the case of the cigar associated with, e.g., the near-horizon…
