On the entropy of strings and branes

Journal of High Energy Physics, 2022
We show that the entropy of strings that wind around the Euclidean time circle is proportional to the Noether charge associated with translations along the T-dual time direction.

Black hole entropy sourced by string winding condensate

Journal of High Energy Physics, 2021
We calculate the entropy of an asymptotically Schwarzschild black hole, using an effective field theory of winding modes in type II string theory. In Euclidean signature, the geometry of the black hole contains a thermal cycle which shrinks towards the ...

Taming boundary condition changing operator anomalies with the tachyon vacuum

Journal of High Energy Physics, 2019
Motivated by the appearance of associativity anomalies in the context of superstring field theory, we give a generalized solution built from boundary condition changing operators which can be associated to a generic tachyon vacuum in the KBc subalgebra ...

Tachyon Condensation in a Chromomagnetic Center Vortex Background

Universe
The chromomagnetic vacuum of SU(2) gluodynamics is considered in the background of a finite radius flux tube (center vortex) with a homogeneous field inside and a zero field outside. In this background, there are tachyonic modes.

Non-invertible symmetries, brane dynamics, and tachyon condensation

Journal of High Energy Physics
We study the Symmetry Topological Field Theory in holography associated with 4d 𝒩 = 1 Super Yang-Mills theory with gauge algebra 𝔰𝔲(M). From this, all the bulk symmetry operators are computed and matched to various D-brane configurations.

Higgs mechanism in nonlocal field theories

Journal of High Energy Physics, 2018
We study spontaneous gauge symmetry breaking and the Higgs mechanism in nonlocal field theories. Motivated by the level truncated action of string field theory, we consider a class of nonlocal field theories with an exponential factor of the d ...

Tachyon Condensation and the Spectrum of Strings on D-Branes [PDF]

Progress of Theoretical Physics, 2001
We investigate spectrum of open strings on D-branes after tachyon condensation in bosonic string theory. We calculate 1-loop partition function of the string and show that its limiting forms coincide with partition functions of open strings with different boundary conditions.

Rolling tachyon and the phase space of open string field theory

Journal of High Energy Physics
We construct the symplectic form on the covariant phase space of the open string field theory on a ZZ-brane in c = 1 string theory, and determine the energy of the rolling tachyon solution, confirming Sen’s earlier proposal based on boundary conformal ...
