D-BRANE CATEGORIES [PDF]

open access: yesInternational Journal of Modern Physics A, 2003
This is an exposition of recent progress in the categorical approach to D-brane physics. I discuss the physical underpinnings of the appearance of homotopy categories and triangulated categories of D-branes from a string field theoretic perspective, and with a focus on applications to homological mirror symmetry.

Non-BPS fractional branes with Bose-Fermi cancellation in asymmetric orbifolds

open access: yesJournal of High Energy Physics, 2018
We study non-BPS D-branes in the type II string vacua with chiral space-time SUSY constructed based on the asymmetric orbifolds of K3≅T4/ℤ2 $$ \mathrm{K}3\cong {T}^4/{\mathrm{\mathbb{Z}}}_2 $$ as a succeeding work of [21].

Entanglement thermodynamics for nonconformal D-branes [PDF]

open access: yes, 2013
We study thermodynamics of entanglement entropy for weakly excited states in certain non-conformal fields theories, whose gravity duals are given by non-conformal Dp-branes.

Dirichlet Branes and Ramond-Ramond charges. [PDF]

open access: yesPhysical Review Letters, 1995
We show that D-branes, extended objects defined by mixed Dirichlet-Neumann boundary conditions, break half the supersymmetries of the type II superstring and carry a complete set of electric and magnetic Ramond-Ramond charges. The product of the electric

BPS D-branes from an Unstable D-brane [PDF]

open access: yesAIP Conference Proceedings, 2005
We search for exact tachyon kink solutions of DBI type effective action describing an unstable D-brane with worldvolume gauge field turned in both the flat and a curved background. There are various kinds of solutions in the presence of electromagnetic fields in the flat space, such as periodic arrays, topological tachyon kinks, half kinks, and bounces.

D-brane actions [PDF]

open access: yesNuclear Physics B, 1996
Effective world-brane actions for solitons of ten-dimensional type IIA and IIB superstring theory are derived using the formulation of solitons as Dirichlet branes. The one-brane actions are used to recover predictions of SL(2,Z) strong-weak coupling duality. The two-brane action, which contains a hidden eleventh target space coordinate, is shown to be

Phase transitions in GLSMs and defects

open access: yesJournal of High Energy Physics, 2021
In this paper, we construct defects (domain walls) that connect different phases of two-dimensional gauged linear sigma models (GLSMs), as well as defects that embed those phases into the GLSMs.
