T-duality and Actions for Non-BPS D-branes [PDF]
, 2000 We employ T-duality to restrict the tachyon dependence of effective actions for non-BPS D-branes. For the Born-Infeld part the criteria of T-duality and supersymmetry are satisfied by a simple extension of the D-brane Born-Infeld action.Comment: Latex ...

, 1995 We discuss duality between Type IIA string theory, eleven-dimensional supergravity, and heterotic string theory in four spacetime dimensions with $N=1$ supersymmetry. We find theories whose infrared limit is trivial at enhanced symmetry points as well as

Journal of High Energy Physics, 2019 We study the general deformation of N $$ \mathcal{N} $$ = 2 supersymmetry transformations of a vector multiplet that forms a (constant) triplet under the SU(2) R-symmetry corresponding to the magnetic dual of the triplet of the Fayet-Iliopoulos (FI ...

Supersymmetry Breaking and Gauge Mediation [PDF]
, 2010 We review recent works on supersymmetry breaking and gauge mediation. We survey our current understanding of dynamical supersymmetry breaking mechanisms and describe new model building tools using duality, meta-stability, and stringy construction.

Surface operators, chiral rings and localization in N $$ \mathcal{N} $$ =2 gauge theories
Journal of High Energy Physics, 2017 We study half-BPS surface operators in supersymmetric gauge theories in four and five dimensions following two different approaches. In the first approach we analyze the chiral ring equations for certain quiver theories in two and three dimensions ...

Black holes in string theory with duality twists
Journal of High Energy Physics, 2020 We consider 5D supersymmetric black holes in string theory compactifications that partially break supersymmetry. We compactify type IIB on T 4 and then further compactify on a circle with a duality twist to give Minkowski vacua preserving partial ...

, 2013 Motivated by the connection between 4-manifolds and 2d N=(0,2) theories, we study the dynamics of a fairly large class of 2d N=(0,2) gauge theories. We see that physics of such theories is very rich, much as the physics of 4d N=1 theories.

Supersymmetry and non-Abelian T-duality in type II supergravity
, 2015 We study the effect of T-duality on supersymmetry in the context of type II supergravity. For both U(1) Abelian and SU(2) non-Abelian T-duality, we demonstrate that the supersymmetry variations after T-duality are related to the variations before T ...

Gaugino condensation, duality and supersymmetry breaking [PDF]
Nuclear Physics B - Proceedings Supplements, 1996 The status of gaugino condensation in low-energy string theory is reviewed. Emphasis is given to the determination of the efective action below condensation scale in terms of the 2PI and Wilson actions. We illustrate how the different perturbative duality symmetries survive this simple nonperturbative phenomenon, providing evidence for the believe that
