Duality without Supersymmetry
I show that physical quantities in several two-dimensional condensed-matter models are related to the Seiberg-Witten calculation of exact quantities in supersymmetric gauge theory. In particular, the magnetization in the Kondo problem and the current in the boundary sine-Gordon model can each be expressed in the form ∫ dx/y, where for example in the latter y = x + x − u with u related to the bo...
متن کاملSelf-duality and Supersymmetry
Chiral/self-dual restrictions of various super Yang-Mills and supergravity theories in (2,2) dimensions are described. These include the N=1 supergravity with a cosmological term and the N=1 new minimal supergravity theory. In the latter case, a self-duality condition on a torsionful Riemann curvature is possible, and it implies the equations of motion that follow from an R 2 type supergravity ...
متن کاملDuality after Supersymmetry Breaking
Starting with two supersymmetric dual theories, we imagine adding a chiral perturbation that breaks supersymmetry dynamically. At low energy we then get two theories with soft supersymmetry-breaking terms that are generated dynamically. With a canonical Kähler potential, some of the scalars of the “magnetic” theory typically have negative mass-squared, and the vector-like symmetry is broken. Si...
متن کاملDuality versus Supersymmetry
We study the effect of S-duality and target-space duality tranformations of N = 4, d = 4 and N = 1, d = 10 supersymmetric configurations on their Killing spinors. We find that, under reasonable assumptions, the dual configurations are also supersymmetric and that the Killing spinors transform in a simple way. There is an increasing interest in finding new classical backgrounds of string theory ...
متن کاملSupersymmetry Without Supersymmetry
We present four-dimensional M -theory vacua with N > 0 supersymmetry which, from the perspective of perturbative Type IIA string theory, have N = 0. Such vacua can appear when the compactifying 7-manifold is a U(1) fibration. The missing superpartners are Dirichlet 0-branes. Someone unable to detect Ramond-Ramond charge would thus conclude that these worlds have no unbroken supersymmetry. In pa...
