In this paper we compute the radiation of the massless closed string states due to the non-vanishing coupling to the rolling open string tachyon with co-dimensions larger than 2, and discuss the effect of back reaction to the motion of the rolling tachyon. We find that for small string coupling, the tachyonic matter remains in the late time, but it will completely evaporate away over a short time of few string scales if the string coupling is huge. Comment on the implication of our results to…

Remarks on Tachyon Driven Cosmology
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 apply this proposal
Electromagnetic string fluid in rolling tachyon
We study Born-Infeld type effective action for unstable D3-brane system including a tachyon and an abelian gauge field, and find the rolling tachyon with constant electric and magnetic fields as the
One-loop evolution of a rolling tachyon
We study the time evolution of the one-loop diagram in Sen's rolling tachyon background. We find that at least in the long cylinder case they grow rapidly at late time, due to the exponential growth
Rolling tachyons and decaying branes
We present new rolling tachyon solutions describing the classical decay of D- branes. Our methods are simpler than those appearing in recent works, yet our results are exact in classical string
The final fate of the rolling tachyon
We propose an alternative interpretation of the boundary state for the rolling tachyon, which may depict the time evolution of unstable D-branes in string theory. Splitting the string variable in the
Tachyon condensation in open-closed p-adic string theory
We study a simple model of p-adic closed and open strings. It sheds some light on the dynamics of tachyon condensation for both types of strings. We calculate the effect of static and decaying
Rolling tachyon with electric and magnetic fields: T-duality approach
We study the decay of unstable D$p$-branes when the world-volume gauge field is turned on. We obtain the relevant Dp-brane boundary state with electric and magnetic fields by boosting and rotating
Thermal partition functions for S-branes
We calculate the thermal partition functions of open strings on the S-brane backgrounds (the bouncing or rolling tachyon backgrounds) both in the bosonic and superstring cases. According to [9], we


Rolling Tachyon
We discuss construction of classical time dependent solutions in open string (field) theory, describing the motion of the tachyon on unstable D-branes. Despite the fact that the string field theory
Tachyon Matter in Boundary String Field Theory
We analyse the classical decay process of unstable D-branes in superstring theory using the boundary string field theory (BSFT) action. We show that the solutions of the equations of motion for the
Rolling tachyon in brane world cosmology from superstring field theory
The pressureless tachyonic matter recently found in superstring field theory has an over-abundance problem in cosmology. We argue that this problem is naturally solved in the brane inflationary
Does the Tachyon Matter
Abstract We study time-dependent solutions of Einstein–Maxwell gravity in four dimensions coupled to tachyon matter—the Dirac–Born–Infeld Lagrangian that provides an effective description of a
Gauge Fields and Scalars in Rolling Tachyon Backgrounds
We investigate the dynamics of gauge and scalar fields on unstable D-branes with rolling tachyons. Assuming an FRW metric on the brane, we find a solution of the tachyon equation of motion which is
Field Theory of Tachyon Matter
We propose a field theory for describing the tachyon on a brane–antibrane system near the minimum of the potential. This field theory realizes two known properties of the tachyon effective action:
