Toda systems in closed string tachyon condensation

چکیده
We consider tt∗ equations appearing in the study of localized tachyon condensations. They are described by various Toda system when we consider the condensation by the lowest tachyon corresponding to the monomial xy. The tachyon potential is calculated as a solution to these equations. The Toda system appearing in the deformation of C/Zn by xy is identical to that of Dn singularity deformed by x. For C /Zn with xyz deformation, we find only generic non-simple form, similar to the case appearing in C/Z5 → C/Z3 and we discuss the difficulties in these cases.

Closed String Tachyon Condensation: An Overview
These notes are an expanded version of a review lecture on closed string tachyon condensation at the RTN workshop in Copenhagen in September 2003. We begin with a lightning review of open string tachyon condensation, and then proceed to review recent results on localized closed string tachyon condensation, focusing on two simple systems, C/Zn orbifolds and twisted circle compactifications.
متن کاملMirror Symmetry and Closed String Tachyon Condensation
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, due to non-renormalization theorems. Moreover, Mirror symmetry sheds light on the RG flow in such cases. We discuss the relevant tachyon condensation in the context of both compact and non-compact s...
متن کاملClosed-String Tachyon Condensation and the On-Shell Effective Action of Open-String Tachyons
We study how the effect of closed-string tachyon condensation can enter into the on-shell effective action of open-string tachyons in the bosonic case. We also consider open-string one-loop quantum corrections to the on-shell action. We use a sigma-model approach with boundary terms, and we utilize some results of boundary string field theory (BSFT) to define the on-shell effective action. We r...
متن کاملThe Schrodinger Wave Functional and Closed String Rolling Tachyon
In this short note we apply Schrodinger picture description of the minisuperspace approach to the closed string tachyon condensation. We will calculate the rate of produced closed string and we will show that the density of high massive closed string modes reaches the string density in time of order one in string units.

متن کاملFate of unoriented bosonic string after tachyon condensation
By a toroidal compactification with a vortex like configuration of tachyon fields, the unoriented bosonic strings in 26 dimensions is equivalent to 10 dimensional string theory with gauge group SO(32)× G where G has rank 16. The reduction from SO(8192) to SO(32) is induced by the action of non-abelian Wilson lines which twists the tachyon. The additional enhanced gauge symmetry G appears from c...
