The Charged Black Hole/String Transition
A. Giveon, D. Kutasov
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 tr…
Non-Supersymmetric Deformations of Non-Critical Superstrings
Nissan Itzhaki, David Kutasov, Nathan Seiberg
We study certain supersymmetry breaking deformations of linear dilaton backgrounds in different dimensions. In some cases, the deformed theory has bulk closed strings tachyons. In…
Accelerating Branes and the String/Black Hole Transition
David Kutasov
String theory in Euclidean flat space with a spacelike linear dilaton contains a D1-brane which looks like a semi-infinite hairpin. In addition to its curved shape, this ``hairpin…
I-Brane Dynamics
Nissan Itzhaki, David Kutasov, Nathan Seiberg
We study the dynamics near a 1+1 dimensional intersection of two orthogonal stacks of fivebranes in type IIB string theory, using an open string description valid at weak coupling,…
