Unoriented D‐brane instantons [PDF]
AbstractWe give a pedagogical introduction to D‐brane instanton effects in vacuum configurations with open and unoriented strings. We focus on quiver gauge theories for unoriented D‐branes at orbifold singularities and describe in some detail the ℤ3 case, where both ‘gauge’ and ‘exotic’ instantons can generate non‐perturbative super potentials, and the

Phase transitions in GLSMs and defects
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.

Dynamics of revolving D-branes at short distances
We study the behavior of the effective potential between revolving Dp-branes at all ranges of the distance r, interpolating r » ls and r « ls (ls is the string length).

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

Hanany-Witten transition in quantum curves
It was known that the U(N )4 super Chern-Simons matrix model describing the worldvolume theory of D3-branes with two NS5-branes and two (1, k)5-branes in IIB brane configuration (dual to M2-branes after taking the T-duality and the M-theory lift ...

(p − 1)-bracket for Dp-branes in large R-R field background
The volume-preserving diffeomorphism is a key feature that characterizes the large constant R-R (p − 1)-form field background in a Dp-brane theory. It represents a symmetry of the theory that preserves the volume of space.

In this note we study the resolution of conifold singularity by D-branes by considering compactification of D-branes on $\C^3/(\Z_2\times\Z_2)$. The resulting vacuum moduli space of D-branes is a toric variety which turns out to be a resolved conifold, that is a nodal variety in $\C^4$. This has the implication that all the corresponding phases of Type-
