Chiral magnets from string theory
Journal of High Energy Physics, 2023 Chiral magnets with the Dzyaloshinskii-Moriya (DM) interaction have received quite an intensive focus in condensed matter physics because of the presence of a chiral soliton lattice (CSL), an array of magnetic domain walls and anti-domain walls, and ...

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

1/2-BPS D-branes from covariant open superstring in AdS4 × CP3 background
Journal of High Energy Physics, 2018 We consider the open superstring action in the AdS4 × CP 3 background and investigate the suitable boundary conditions for the open superstring describing the 1/2-BPS D-branes by imposing the κ-symmetry of the action.

Notes on worldvolume supersymmetries for D-branes on AdS5×S5 background
Journal of High Energy Physics, 2017 We revisit the 1/2-BPS D-branes on the AdS5×S5 background. Based only on the classification of 1/2-BPS D-branes obtained by the covariant open string description, we consider various purely static configurations of D-branes without any worldvolume flux ...

Lattice black branes at large D
Journal of High Energy Physics, 2022 We explore the phase space of non-uniform black branes compactified on oblique lattices with a large number of dimensions. We find the phase diagrams for different periodicities and angles, and determine the thermodynamically preferred phases for each ...

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

Phase transitions in GLSMs and defects
Journal 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.

SciPost Physics, 2022 We study correlation functions of D-branes and a supergravity mode in AdS, which are dual to structure constants of two sub-determinant operators with large charge and a BPS single-trace operator. Our approach is inspired by the large charge expansion

Unitarity, D-brane dynamics and D-brane categories [PDF]
Journal of High Energy Physics, 2001 This is a short nontechnical note summarizing the motivation and results of my recent work on D-brane categories. I also give a brief outline of how this framework can be applied to study the dynamics of topological D-branes and why this has a bearing on the homological mirror symmetry conjecture. This note can be read without any knowledge of category

Journal of High Energy Physics, 2004 We study several different kinds of bound states built from D-branes and orientifolds. These states are to atoms what branonium - the bound state of a brane and its anti-brane - is to positronium, inasmuch as they typically involve a light brane bound to a much heavier object with conserved charges which forbid the system's decay.
