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 ...

Tachyon condensation on a noncommutative torus [PDF]
Physical Review D, 2001 We discuss noncommutative solitons on a noncommutative torus and their application to tachyon condensation. In the large B limit, they can be exactly described by the Powers-Rieffel projection operators known in the mathematical literature. The resulting soliton spectrum is consistent with T-duality and is surprisingly interesting.

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 ...

Remarks on Black Hole Instabilities and Closed String Tachyons [PDF]
, 2002 Physical arguments stemming from the theory of black-hole thermodynamics are used to put constraints on the dynamics of closed-string tachyon condensation in Scherk--Schwarz compactifications.

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.
