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 ...

Bianchi Type‐I Bulk Viscosity with a DE Cosmological Model

Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020
The finding article presents Bianchi type‐I universe in the presence of bulk viscous and DE fluid nature of a cosmological model. The solutions of field equations were obtained by assuming hybrid expansion law. The physical significance of the obtained findings illustrates the dominance of bulk viscosity in early and dominance of dark energy fluid ...

On condensation of closed-string tachyons [PDF]

Nuclear Physics B, 2002
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 of tachyon condensation is thus expected to be the vacuum of Type-IIB superstring.

LREE of a dynamical unstable Dp-brane

Nuclear Physics B, 2020
We derive the left-right entanglement entropy (LREE) for a bosonic Dp-brane. This brane has tangential dynamics and has been dressed by a U(1) gauge potential, the Kalb-Ramond field and a tachyon field.

Carroll limit of non-BPS Dp-brane

Journal of High Energy Physics, 2017
We find Carroll non-BPS Dp-brane action by performing Carroll limit of a canonical form of unstable Dp-brane action. We analyze different Carroll limits and discuss solutions of the equations of motion of Carroll non-BPS Dp-brane at the tachyon vacuum.
