Gauge fields and D-branes [PDF]
Journal of Geometry and Physics, 1998 We prove that self-dual gauge fields in type I superstring theory are equivalent to configurations of Dirichlet 5-branes, by showing that the world-sheet theory of a Dirichlet 1-brane moving in a background of 5-branes includes an ``ADHM sigma model.'' This provides an explicit construction of the equivalent self-dual gauge field.

D-branes on K3-fibrations [PDF]
Nuclear Physics B, 2000 B-type D-branes are constructed on two different K3-fibrations over IP_1 using boundary conformal field theory at the rational Gepner points of these models. The microscopic CFT charges are compared with the Ramond charges of D-branes wrapped on holomorphic cycles of the corresponding Calabi-Yau manifold.

D-branes in AdS3 × S3 × 𝕋4 at k = 1 and their holographic duals [PDF]
Journal of High Energy Physics, 2021 String theory on AdS3× S3× 𝕋4 with minimal k = 1 NS-NS flux can be described in terms of a free field worldsheet theory in the hybrid formalism. We construct various D-branes of this string theory and calculate their associated cylinder amplitudes.

D-Branes in Para-Hermitian Geometries
Universe, 2022 We introduce T-duality invariant versions of D-branes in doubled geometry using a global covariant framework based on para-Hermitian geometry and metric algebroids.

A novel solution to the gravitino problem
Journal of High Energy Physics, 2023 In a general phenomenological model with local supersymmetry, the amount of massive gravitinos produced in early universe tends to violate the known dark matter density bound by many orders of magnitude.

Journal of High Energy Physics, 2000 We study D-branes on the quintic CY by combining results from several directions: general results on holomorphic curves and vector bundles, stringy geometry and mirror symmetry, and the boundary states in Gepner models recently constructed by Recknagel and Schomerus, to begin sketching a picture of D-branes in the stringy regime.

Aspects of categorical symmetries from branes: SymTFTs and generalized charges [PDF]
SciPost Physics, 2023 Recently it has been observed that branes in geometric engineering and holography have a striking connection with generalized global symmetries. In this paper we argue that branes, in a certain topological limit, not only furnish the symmetry generators,

Nuclear Physics B, 1997 We present a manifestly Lorentz invariant, spacetime supersymmetric, and `$ $-invariant' worldvolume action for all type II Dirichlet p-branes, $p\le9$, in a general type II supergravity background, including massive backgrounds in the IIA case. The $p=0,2$ cases are rederived from D=11.
