Rotating NS5-brane solution and its exact string theoretical description
Abstract
We construct the most general solution in type-II string theory that represents N coincident non-extremal rotating NS5-branes and determine the relevant thermodynamic quantities. We show that in the field theory limit, it has an exact description. In particular, it can be obtained by an O(3,3) duality transformation on the exact string background for the coset model SL(2,R)-N/U(1) × SU(2)N. In the extreme supersymmetric limit we recover the multicenter solution, with a ring singularity structure, that has been discussed recently.
