چکیده

The Supersymmetric Dual Sigma Model (SDSM) is a local field theory introduced to be nonlocally equivalent to the Supersymmetric Chiral nonlinear σ-Model (SCM), this dual equivalence being proven by explicit canonical transformation in tangent space. This model is here reconstructed in superspace and identified as a chiral-entwined supersymmetrization of the Dual Sigma Model (DSM). This analysis sheds light on the boson-fermion symphysis of the dual transition, and on the new geometry of the DSM.

Canonical Equivalence of Non-isometric Σ-models and Poisson–lie T-duality

We prove that a transformation, conjectured in our previous work, between phase-space variables in σ-models related by Poisson–Lie T-duality is indeed a canonical one. We do so by explicitly demonstrating the invariance of the classical Poisson brackets. This is the first example of a class of σ-models with no isometries related by canonical transformations. In addition we discuss generating fu...

Dedicated to the Memory of Abdus Salam

This review considers the properties of classical solutions to supergravity theories with partially unbroken supersymmetry. These solutions saturate Bogomol’nyPrasad-Sommerfield bounds on their energy densities and are the carriers of the p-form charges that appear in the supersymmetry algebra. The simplest such solutions have the character of (p + 1)-dimensional Poincaré-invariant hyperplanes ...

Duality and Restoration of Manifest Supersymmetry

World–sheet and spacetime supersymmetries that are manifest in some string backgrounds may not be so in their T–duals. Nevertheless, they always remain symmetries of the underlying conformal field theory. In previous work the mechanism by which T–duality destroys manifest supersymmetry and gives rise to non–local realizations was found. We give the general conditions for a 2-dim N = 1 supersymm...

Geometric Metastability, Quivers and Holography

We use large N duality to study brane/anti-brane configurations on a class of CalabiYau manifolds. With only branes present, the Calabi-Yau manifolds in question give rise to N = 2 ADE quiver theories deformed by superpotential terms. We show that the large N duality conjecture of [1] reproduces correctly the known qualitative features of the brane/anti-brane physics. In the supersymmetric case...
