Tachyon condensation in magnetic compactifications [PDF]
Journal of High Energy Physics, 2021 Intersecting D-brane models and their T-dual magnetic compactifications provide an attractive framework for particle physics, allowing for chiral fermions and supersymmetry breaking.

Dynamical Cobordism and the beginning of time: supercritical strings and tachyon condensation
Journal of High Energy Physics, 2022 We describe timelike linear dilaton backgrounds of supercritical string theories as time-dependent Dynamical Cobordisms in string theory, with their spacelike singularity as a boundary defining the beginning of time.

Particle Production in Tachyon Condensation [PDF]
Journal of High Energy Physics, 2004 We study particle production in the tachyon condensation process as described by different effective actions for the tachyon. By making use of invariant operators, we are able to obtain exact results for the density of produced particles, which is shown to depend strongly on the specific action.

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

Thermodynamics and tachyon condensation of the dressed-dynamical unstable Dp-branes
European Physical Journal C: Particles and Fields, 2023 Using the boundary state formalism and thermo field dynamics approach, we study a Dp-brane at finite temperature in which the background Kalb–Ramond field, a U(1) gauge potential, and tachyon field are turned on together with a general tangential ...

Inhomogeneous tachyon condensation [PDF]
Journal 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 near local minima.

Confinement of Fermions in Tachyon Matter
Advances 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 ...

Tachyon condensation in superstring field theory [PDF]
Nuclear Physics B, 2000 It has been conjectured that at the stationary point of the tachyon potential for the D-brane-anti-D-brane pair or for the non-BPS D-brane of superstring theories, the negative energy density cancels the brane tensions. We study this conjecture using a Wess-Zumino-Witten-like open superstring field theory free of contact term divergences and recently ...

Brane with transverse rotation and background fields: boundary state and tachyon condensation
European Physical Journal C: Particles and Fields, 2020 The boundary state corresponding to the Dp-brane with a transverse rotation in the presence of the Kalb–Ramond and tachyon background fields and a U(1) internal field will be constructed.
