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.

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).

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 ...

Reheating from Tachyon Condensation [PDF]
Journal of High Energy Physics, 2002 We argue that it may be possible to reheat the universe after inflation driven by D-brane annihilation, due to the coupling of massless fields to the time-dependent tachyon condensate which describes the annihilation process. This mechanism can work if the original branes annihilate to a stable brane containing the standard model.

Note on light-like tachyon condensation [PDF]
Journal of High Energy Physics, 2010 In this paper closed string emission and open string pair production from the light-like rolling tachyon solution are calculated in subcritical string theory in the background of a linear dilaton. The rolling light-like tachyon represents the inhomogeneous decay of unstable D-brane. The decay rate is given by the imaginary part of annulus diagram which

ADHM is tachyon condensation [PDF]
Journal of High Energy Physics, 2006 We completely realize the ADHM construction of instantons in D-brane language of tachyon condensations. Every step of the construction is given a physical interpretation in string theory, in a boundary state formalism valid all order in α'. Accordingly, equivalence between Yang-Mills configurations on D4-branes and D0-branes inside the D4-branes is ...

LREE of an unstable dressed-dynamical Dp-brane: superstring calculations
European Physical Journal C: Particles and Fields, 2021 We obtain the left-right entanglement entropy (LREE) for a Dp-brane with tangential motion in the presence of a U(1) gauge potential, the Kalb–Ramond field and an open string tachyon field. Thus, at first we extract the Rényi entropy and then by taking a
