Tachyon condensation in magnetic compactifications [PDF]

open access: yesJournal 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.

LREE of an unstable dressed-dynamical Dp-brane: superstring calculations

open access: yesEuropean 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

Dynamical Cobordism and the beginning of time: supercritical strings and tachyon condensation

open access: yesJournal 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.

Canonical analysis of geometrical action for Dp-brane

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
In this short note we perform canonical analysis of geometrical action for Dp-brane. We also discuss tachyon condensation in case of the geometrical action for unstable D(p+1)-brane.

Thermodynamics and tachyon condensation of the dressed-dynamical unstable Dp-branes

open access: yesEuropean 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 ...

Note about D-branes in Carrollian background

open access: yesJournal of High Energy Physics, 2022
This paper is devoted to the construction of stable and unstable Dp-branes in generalized Carroll space-times. We also study tachyon solutions on the world-volume of unstable Dp-brane in Carrollian background and discuss their physical interpretations.

Brane with transverse rotation and background fields: boundary state and tachyon condensation

open access: yesEuropean 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.

Tachyon condensation and Boundary States in Bosonic String [PDF]

open access: yes, 2000
We discuss tachyon configuration for the unoriented bosonic string theory which produces a bosonic string theory with SO(32) gauge symmetry in ten dimensions. It is closely related to the tachyon condensation scenario proposed by A. Sen. We also give the

Probing tachyon kinks in Newton-Cartan background

open access: yesPhysics Letters B, 2019
In this paper, we perform a systematic analysis of tachyon condensation over string Newton-Cartan (NC) geometry by probing the background with non BPS Dp brane.

Note about covariant Hamiltonian formalism for strings, p-branes and unstable Dp-branes

open access: yesPhysics Letters B, 2020
In this short note we formulate Covariant Hamiltonian formalism for strings, p-branes and Non-BPS Dp-branes. We also analyse the vacuum tachyon condensation in case of unstable D1-brane.
