Unity of Supersymmetry Breaking Models [PDF]
We examine the models with gauge group U(1)^{k-1}\times\prod_{i=1}^k SU(n_i), which are obtained from decomposing the supersymmetry breaking model of Affleck, Dine and Seiberg containing an antisymmetric tensor field. We note that all of these models are

T-duality and Actions for Non-BPS D-branes [PDF]
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 ...

N = (4,4) Supersymmetry and T-Duality [PDF]
A sigma model with four-dimensional target space parametrized by chiral and twisted chiral N =(2,2) superfields can be extended to N =(4,4) supersymmetry off-shell, but this is not true for a model of semichiral fields, where the N = (4,4) supersymmetry can only be realized on-shell. The two models can be related to each other by T-duality.

The action with manifest E7 type symmetry
We generalize Cremmer-Julia 1st order action of N = 8 $$ \mathcal{N}=8 $$ supergravity with manifest E 7(7) symmetry to cases of N = 6 $$ \mathcal{N}=6 $$ with manifest SO∗(12) and N = 5 $$ \mathcal{N}=5 $$ with manifest SU(1, 5) duality symmetries ...

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 ...

Self-duality and supersymmetry
We observe that the Hamiltonian H = D^2, where D is the flat 4d Dirac operator in a self-dual gauge background, is supersymmetric, admitting 4 different real supercharges. A generalization of this model to the motion on a curved conformally flat 4d manifold exists.

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

Surface operators, chiral rings and localization in N $$ \mathcal{N} $$ =2 gauge theories
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
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 ...

T-duality and Generalized Complex Geometry [PDF]
We find the explicit T-duality transformation in the phase space formulation of the N=(1,1) sigma model. We also show that the T-duality transformation is a symplectomorphism and it is an element of O(d,d).
