Remarks on Tachyon Driven Cosmology
Ashoke Sen
We begin by reviewing the results on the decay of unstable D-branes in type II string theory, and the open-closed string duality proposal that arises from these studies. We then ap…
Moduli Space of Unstable D-branes on a Circle of Critical Radius
Ashoke Sen
We study the moduli space of the boundary conformal field theories describing an unstable D-brane of type II string theory compactified on a circle of critical radius. This moduli…
Open-Closed Duality: Lessons from Matrix Model
Ashoke Sen
Recent investigations involving the decay of unstable D-branes in string theory suggest that the tree level open string theory which describes the dynamics of the D-brane already k…
Open-Closed Duality at Tree Level
Ashoke Sen
We study decay of unstable D-branes in string theory in the presence of electric field, and show that the classical open string theory results for various properties of the final s…
Open and Closed Strings from Unstable D-branes
Ashoke Sen
The tachyon effective field theory describing the dynamics of a non-BPS D--brane has electric flux tube solutions where the electric field is at its critical value and the tachy…
Dirac-Born-Infeld Action on the Tachyon Kink and Vortex
Ashoke Sen
The tachyon effective field theory describing the dynamics of a non-BPS D-brane in superstring theory has an infinitely thin but finite tension kink solution describing a codimensi…
