On Solvable Time-Dependent Model and Rolling Closed String Tachyon
We investigate the SL(2,R)/U(1) WZW model with level 0 < k < 2 as a solvable time-dependent background in string theory. This model is expected to be dual to the one describing a rolling closed string tachyon with a time-like linear dilaton. We examine its exact metric and minisuperspace wave functions. Two point functions and the oneloop vacuum amplitude are computed and their relation to the ...
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 کاملToward Open-Closed String Theoretical Description of Rolling Tachyon
We consider how the time-dependent decay process of an unstable D-brane should be described in the full (quantum) open-closed string theory. It is argued that the system, starting from the unstable D-brane configuration, will evolve in time into the time-independent open string tachyon vacuum configuration which we assume to be finite, with the total energy conserved. As a concrete realization ...
متن کاملA Closed String Tachyon Vacuum ?
In bosonic closed string field theory the " tachyon potential " is a potential for the tachyon, the dilaton, and an infinite set of massive fields. Earlier computations of the potential did not include the dilaton and the critical point formed by the quadratic and cubic interactions was destroyed by the quartic tachyon term. We include the dilaton contributions to the potential and find that a ...
متن کاملOn Closed String Tachyon Dynamics
We study the condensation of closed string tachyons as a time-dependent process. In particular, we study tachyons whose wave functions are either space-filling or localized in a compact space, and whose masses are small in string units; our analysis is otherwise general and does not depend on any specific model. Using world-sheet methods, we calculate the equations of motion for the coupled tac...
