An exact cubic open string field theory rolling tachyon solution was recently found by Kiermaier et. al. and Schnabl. This oscillatory solution has been argued to be related by a field redefinition… (More)

Disorder on the string theory landscape may significantly affect dynamics of eternal inflation leading to the possibility for some vacua on the landscape to become dynamically preferable over others.… (More)

In this paper, we study the fate of the holographic zero sound mode at finite temperature and non-zero baryon density in the deconfined phase of the Sakai-Sugimoto model of holographic QCD. We… (More)

We study the tree level scattering or emission of n closed superstrings from a decaying non-BPS brane in Type II superstring theory. We attempt to calculate generic n-point superstring disk… (More)

We investigate the flow of a strongly coupled anyonic superfluid based on the holographic D3-D7’ probe brane model. By analyzing the spectrum of fluctuations, we find the critical superfluid… (More)

It has long been known that there is a relation between boundary sineGordon theory and thermodynamics of charge neutral two-component Coulomb plasma on a unit circle. On the other hand, recently it… (More)

We show that the open string worldsheet description of brane decay (discussing a specific example of a rolling tachyon background) can be related to a sequence of points of thermodynamic equilibrium… (More)

We study n-point boundary correlation functions in Timelike Boundary Liouville theory, relevant for open string multiproduction by a decaying unstable D-brane. We give an exact result for the… (More)

We study the process of inhomogeneous tachyon condensation in an intersecting D1and anti-D1-brane system using an effective tachyon DBI action. By switching to the Hamiltonian formalism, we… (More)

At high enough charge density, the homogeneous state of the D3-D7’ model is unstable to fluctuations at nonzero momentum. We investigate the end point of this instability, finding a spatially… (More)
