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…
On tachyons, gauged linear sigma models, and flip transitions
- Physics

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

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…
Closed bosonic string field theory at quartic order

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…

- 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…

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

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…
Tachyon condensation and black hole entropy.

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.
