Non-invertible symmetries, brane dynamics, and tachyon condensation
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.

ADHM is tachyon condensation [PDF]
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
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

Loop corrected tachyon condensation [PDF]
We study loop corrections in boundary string field theory (BSFT). After commenting on problems with quantizing the tree level BSFT as an ordinary field theory, we discuss the tree level coupling to closed strings and define the loop corrections via factorization in the closed string channel.

Cosmological signature of tachyon condensation [PDF]
We consider the dynamics of the open string tachyon condensation in a framework of the cubic fermionic String Field Theory including a non-minimal coupling with closed string massless modes, the graviton and the dilaton. Coupling of the open string tachyon and the dilaton is motivated by the open String Field Theory in a linear dilaton background and ...

Aspects of finite temperature corrections in string theory [PDF]
PhDIn this thesis some aspects of temperature corrections in string theory are analyzed: in particular, we study the thermal contributions to the 4 dimensional effective potential arising from string theory compactifications.

Area Law Saturation of Entropy Bound from Perturbative Unitarity in Renormalizable Theories
Abstract We study the quantum information storage capacity of solitons and baryons in renormalizable quantum field theories that do not include gravity. We observe that a 't Hooft‐Polyakov magnetic monopole saturates the Bekenstein bound on information when the theory saturates the bound on perturbative unitarity.

TACHYON CONDENSATES AND ANISOTROPIC UNIVERSE [PDF]
We investigate the cosmological solutions in closed bosonic string theory in the presence of nonzero tachyon condensate. We specifically obtain time-dependent solutions which describes an anisotropic universe. We also discuss the nature of such time-dependent solutions when small tachyon fluctuations around the condensate are taken into account.
