In this paper, the authors derived equations of motion for the tachyon field living on an unstable non-BPS D-brane in the level truncated open cubic superstring field theory.Abstract:
We derive equations of motion for the tachyon field living on an unstable non-BPS D-brane in the level truncated open cubic superstring field theory in the first non-trivial approximation. We construct a special time dependent solution to this equation which describes a rolling tachyon. It starts from the perturbative vacuum and approaches one of stable vacua in infinite time. We investigate conserved energy functional and show that its different parts dominate in different stages of the evolution. We show that the pressure for this solution has its minimum at zero time and goes to minus energy at infinite time.read more

Liouville Field Theory — A decade after the revolution
TL;DR: In this paper, a review of the recent developments of the Liouville field theory and its matrix model dual is presented, which includes some original material such as the derivation of the conjectured dual action for the N = 2 LiOUville theory from other known dualities and the comparison of the cross-cap state with the c = 0 unoriented matrix model.

Closed strings from decaying D-branes
TL;DR: In this paper, the authors compute the emission of closed string radiation from homogeneous rolling tachyons, and show that for an unstable decaying Dp-brane, the radiated energy is infinite to leading order for p ≤ 2 and finite for 2$>p > 2.

D-brane decay in two-dimensional string theory
TL;DR: In this article, the authors considered unstable D0-branes of two-dimensional string theory, described by the boundary state of Zamolodchikov and Verlinde [36] multiplied by the Neumann boundary state for the time coordinate t. This coherent state agrees with the exponential of the closed string one-point function on a disk with Sen's marginal boundary interaction for t which describes D-brane decay.

Tachyon Matter
TL;DR: In this article, it was shown that classical decay of unstable D-branes in bosonic and superstring theories produces pressureless gas with non-zero energy density, and that energy density is stored in the open string fields, even though around the minimum of the tachyon potential there are no open string degrees of freedom.

Brane Inflation

TL;DR: In this paper, a novel inflationary scenario in theories with low-scale (TeV) quantum gravity was presented, in which the standard model particles are localized on the branes whereas gravity propagates in the bulk of large extra dimensions.
