String Theory in Rolling Tachyon Vacuum
Ashoke Sen
We suggest that the universe filled with unstable D-branes in their rolling tachyon vacuum state, described by periodic arrays of D-instantons along the imaginary time direction, m…

Instantons in sine-Liouville theory
Sergei Alexandrov, Raghu Mahajan, Ashoke Sen
We compute instanton corrections to the partition function of sine-Liouville (SL) theory, which provides a worldsheet description of two-dimensional string theory in a non-trivial…

Time and Tachyon
Ashoke Sen
Recent analysis suggests that the classical dynamics of a tachyon on an unstable D-brane is described by a scalar Born-Infeld type action with a runaway potential. The classical co…
