Tachyon Condensation with B-field [PDF]

open access: yesJournal of High Energy Physics, 2006
We discuss classical solutions of a graviton-dilaton-B_{\mu\nu}-tachyon system. Both constant tachyon solutions, including AdS_3 solutions, and space-dependent tachyon solutions are investigated, and their possible implications to closed string tachyon ...

Inhomogeneous tachyon condensation [PDF]

open access: yesJournal of High Energy Physics, 2009
We investigate the spacetime-dependent condensation of the tachyon in effective field theories. Previous work identified singularities in the field which appear in finite time: infinite gradients at the kinks, and (in the eikonal approximation) caustics ...

The (De)confinement Transition in Tachyonic Matter at Finite Temperature

open access: yesAdvances in High Energy Physics, 2019
We present a QCD motivated model that mimics QCD theory. We examine the characteristics of the gauge field coupled with the color dielectric function (G) in the presence of temperature (T).

Closed String Tachyon Condensation: An Overview [PDF]

open access: yesClassical and Quantum Gravity, 2004
These notes are an expanded version of a review lecture on closed string tachyon condensation at the RTN workshop in Copenhagen in September 2003. We begin with a lightning review of open string tachyon condensation, and then proceed to review recent ...

Confinement of Fermions in Tachyon Matter

open access: yesAdvances in High Energy Physics, 2020
In this paper, we develop a phenomenological model inspired by QCD that mimics the QCD theory. We use the gauge theory in color dielectric medium (Gϕ) coupled with fermion fields to produce scalar and vector confinements in the chromoelectric flux tube ...

Cosmological tachyon condensation [PDF]

open access: yesPhysical Review D, 2009
We consider the prospects for dark matter/energy unification in k-essence type theories. General mappings are established between the k-essence scalar field, the hydrodynamic and braneworld descriptions.

Exact Tachyon Condensation on Noncommutative Torus [PDF]

open access: yesJournal of High Energy Physics, 2001
We construct the exact noncommutative solutions on tori. This gives an exact description of tachyon condensation on bosonic D-branes, non-BPS D-branes and brane-antibrane systems. We obtain various bound states of D-branes after the tachyon condensation.

Cosmological Signature of Tachyon Condensation [PDF]

open access: yesJournal of High Energy Physics, 2008
We consider the dynamics of the open string tachyon condensation in a framework of the cubic fermionic String Field Theory including a non-minimal coupling with closed string massless modes, the graviton and the dilaton.

On Condensation of Closed-string Tachyons [PDF]

open access: yesNuclear Physics B, 2001
An F-theory dual of a nonsupersymmetric orientifold is considered. It is argued that the condensation of both open and closed string tachyons in the orientifold corresponds to the annihilation of branes and anti-branes in the F-theory dual. The end-point

Closed string tachyon condensation revisited

open access: yesJournal of High Energy Physics
We consider condensation of nearly marginal matter tachyons in closed string field theory and observe that upon restricting to a subspace of states not containing the ghost dilaton, the on-shell value of the action is proportional to the shift of the ...
