### On tachyons in generic orbifolds of Bbb Cr and gauged linear sigma models

- Mathematics
- 2007

We study some aspects of Gauged Linear Sigma Models corresponding to orbifold singularities of the form r/Γ, for r = 2,3 and Γ = n and n × m. These orbifolds might be tachyonic in general. We compute…

### The Coulomb branch in gauged linear sigma models

- Physics
- 2005

We investigate toric GLSMs as models for tachyon condensation in type II strings on space-time non-supersymmetric orbifold singularities. The A-model correlators in these theories satisfy a set of…

- Physics
- 2005

We study systems of multiple localized closed string tachyons and the phenomena associated with their condensation, in 3/N nonsupersymmetric noncompact orbifold singularities using gauged linear…

### Closed string tachyons, flips and conifolds

- Mathematics
- 2006

Following the analysis of tachyons and orbifold flips described in hep-th/0412337, we study nonsupersymmetric analogs of the supersymmetric conifold singularity and show using their toric geometry…

### On phases of generic toric singularities

- Mathematics
- 2007

We systematically study the phases of generic toric singularities, using methods initiated in hep-th/0612046. These correspond to large volume limits of certain Gauged Linear Sigma Models. We show…

### Nothing for branes

- Physics
- 2007

Recent work on closed string tachyon condensation suggests the existence of a 'nothing state' where closed strings and space itself vanish. We consider the evolution of D-branes in such condensation…

We explore the phase structure induced by closed string tachyon condensation of toric nonsupersymmetric conifold-like singularities described by an integral charge matrix Q=(n{sub 1}n{sub 2}-n{sub…

We give a complete numerical description of the geometry of the four-point contact interaction of closed bosonic string field theory. Namely, we compute the boundary of the relevant region of the…

### Profiling the brane drain in a nonsupersymmetric orbifold

- Physics
- 2005

We study D-branes in a nonsupersymmetric orbifold of type 2/Γ, perturbed by a tachyon condensate, using a gauged linear sigma model. The RG flow has both Higgs and Coulomb branches, and each branch…

- Mathematics
- 2008

We study (0,2) deformations of = 2 Liouville field theory and its mirror duality. A gauged linear sigma model construction of the ultraviolet theory connects (0,2) deformations of Liouville field…

### Mirror Symmetry and Closed String Tachyon Condensation

- Physics
- 2001

We study closed string tachyon condensation using the RG flow of the worldsheet theory. In many cases the worldsheet theory enjoys N=2 supersymmetry, which provides analytic control over the flow,…

### Twisted tachyon condensation in closed string field theory

- Physics, Mathematics
- 2004

We consider twisted tachyons on /N orbifolds of bosonic closed string theory. It has been conjectured that these tachyonic instabilities correspond to decays of the orbifolds into flat space or into…

- Mathematics
- 2001

We propose a closed string tachyon action including kinetic and potential terms for non-supersymmetric orbifolds. The action is given in terms of solutions to tt* equations which captures the…

### Localized Tachyons and the Quantum McKay Correspondence

- Physics
- 2004

The condensation of closed string tachyons localized at the fixed point of a d/Γ orbifold can be studied in the framework of renormalization group flow in a gauged linear sigma model. The evolution…

### Resolution of Orbifold Singularities in String Theory

- Mathematics
- 1994

In this paper the relationship between the classical description of the resolution of quotient singularities and the string picture is reviewed in the context of N=(2,2) superconformal field…

### On Decay of K-theory

- Physics
- 2002

Closed string tachyon condensation resolves the singularities of nonsupersymmetric orbifolds, however the resolved space typically has fewer D-brane charges than that of the orbifold. The description…

The entropy computed using the recent results on condensation of twisted-sector tachyons in this theory is found to be in precise agreement with the Bekenstein-Hawking entropy.
