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…
A Geometric Interpretation of the Open String Tachyon
D. Kutasov
Unstable, non-BPS D-branes in weakly coupled ten dimensional string theory have many mysterious properties. Among other things, it is not clear what sets their tension, what is the…
D-Brane Dynamics Near NS5-Branes
D. Kutasov
We use the Dirac-Born-Infeld action to study the real time dynamics of a -brane propagating in the vicinity of -branes. This problem is closely related to tachyon condensa…
New Results on the "-theorem" in Four Dimensional Supersymmetric Field Theory
D. Kutasov
In four dimensional N=1 supersymmetric field theory it is often the case that the current that becomes part of the superconformal algebra at the infrared fixed point is co…
A New Hat For The c=1 Matrix Model
M. R. Douglas, I. R. Klebanov, D. Kutasov +3
We consider two dimensional supergravity coupled to matter. This system can also be interpreted as noncritical type 0 string theory in a two dimensional target space. Af…
Localized Tachyons and RG Flows
Jeffrey A. Harvey, David Kutasov, Emil J. Martinec +1
We study condensation of closed string tachyons living on defects, such as orbifold fixed planes and Neveu-Schwarz fivebranes. We argue that the high energy density of localized st…
