Rolling Closed String Tachyons and the Big Crunch
We study the low-energy effective field equations that couple gravity, the dilaton, and the bulk closed string tachyon of bosonic closed string theory. We establish that whenever the tachyon induces the rolling process, the string metric remains fixed while the dilaton rolls to strong coupling. For negative definite potentials we show that this results in an Einstein metric that crunches the un...
متن کاملRolling Tachyons in String Cosmology
We study the role of rolling tachyons in the cosmological model with dilatonic gravity. In the string frame, flat space solutions of both initial-stage and late-time are obtained in closed form. In the Einstein frame, we show that every expanding solution is decelerating.
متن کاملSingularities and Closed String Tachyons
A basic problem in gravitational physics is the resolution of spacetime singularities where general relativity breaks down. The simplest such singularities are conical singularities arising from orbifold identifications of flat space, and the most challenging are spacelike singularities inside black holes (and in cosmology). Topology changing processes also require evolution through classically...
متن کاملSupersymmetric fluxbrane intersections and closed string tachyons
We consider NS-NS superstring model with several “magnetic” parameters bs (s = 1, ..., N) associated with twists mixing a compact S direction with angles in N spatial 2-planes of flat 10-dimensional space. It generalizes the Kaluza-Klein Melvin model which has single parameter b. The corresponding U-dual background is a R-R type IIA solution describing an orthogonal intersection of N flux 7-bra...
متن کاملClosed string tachyons, flips and conifolds
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 description that they are nonsupersymmetric orbifolds of the latter. Using linear sigma models, we see that these are unstable to localized closed string tachyon condensation and exhibit flip transiti...
