Delocalized, non-SUSY p-branes, tachyon condensation and tachyon matter [PDF]

, 2004
We construct non-supersymmetric p-brane solutions of type II supergravities in arbitrary dimensions (d) delocalized in one of the spatial transverse directions.

Magnetic catalysis and the chiral condensate in holographic QCD

Journal of High Energy Physics, 2020
We investigate the effect of a non-zero magnetic field on the chiral condensate using a holographic QCD approach. We extend the model proposed by Iatrakis, Kiritsis and Paredes in [1] that realises chiral symmetry breaking dynamically from 5d tachyon ...

One loop partition function in the presence of tachyon background and corrections to tachyon condensation [PDF]

, 2001
We compute the one-loop partition function for quadratic tachyon background in open string theory. Both closed and open string representations are developed.

On the entropy of strings and branes

Journal of High Energy Physics, 2022
We show that the entropy of strings that wind around the Euclidean time circle is proportional to the Noether charge associated with translations along the T-dual time direction.

Tachyon Condensation in a Chromomagnetic Center Vortex Background

Universe
The chromomagnetic vacuum of SU(2) gluodynamics is considered in the background of a finite radius flux tube (center vortex) with a homogeneous field inside and a zero field outside. In this background, there are tachyonic modes.

Taming boundary condition changing operator anomalies with the tachyon vacuum

Journal of High Energy Physics, 2019
Motivated by the appearance of associativity anomalies in the context of superstring field theory, we give a generalized solution built from boundary condition changing operators which can be associated to a generic tachyon vacuum in the KBc subalgebra ...

Black hole entropy sourced by string winding condensate

Journal of High Energy Physics, 2021
We calculate the entropy of an asymptotically Schwarzschild black hole, using an effective field theory of winding modes in type II string theory. In Euclidean signature, the geometry of the black hole contains a thermal cycle which shrinks towards the ...

Tachyon condensation on torus and T-duality [PDF]

Journal of High Energy Physics, 2008
We find an exact solution, with a nonzero net D-brane charge, in the boundary string field theory of brane-anti-brane pairs on a torus. We explicitly take the T-dual of this configuration. The Nahm-transformation of the instantons is derived from the tachyon condensation.

Closed String Tachyon Condensation at c =1

, 2019
The c=1 matrix model, with or without a type 0 hat, has an exact quantum solution corresponding to closed string tachyon condensation along a null surface. The condensation occurs, and spacetime dissolves, at a finite retarded time on I+.

Tachyon Condensation on Separated Brane-Antibrane System [PDF]

, 2008
We study the effect of tachyon condensation on a brane antibrane pair in superstring theory separated in the transverse direction. The static properties of the tachyon potential analyzed using level truncated string field theory reproduces the desired ...
