supersymmetric σ - models
Supersymmetric non–linear σ–models are described by a field dependent Kähler metric determining the kinetic terms. In general it is not guaranteed that this metric is always invertible. Our aim is to investigate the symmetry structure of supersymmetric models in four dimensional space-time in which metric singularities occur. For this purpose we study a simple anomaly-free extension of the supe...
متن کاملNon – linear supersymmetric σ – Model for Scalar Classical Waves
We derive a non–linear supersymmetric σ–model for the transport of light (classical waves) through a disordered medium. We compare this model with the well–established non–linear σ–model for the transport of electrons (Schrödinger waves) and display similarities of and differences between both cases. We show that for weak disorder, both models are equivalent (have the same effective Lagrangean)...
متن کاملGauging N=2 Supersymmetric Non-Linear σ-Models in the Atiyah-Ward Space-Time
We build up a class of N=2 supersymmetric non-linear σ-models in an N=1 superspace based on the Atiyah-Ward space-time of (2+2)–signature metric. We also discuss the gauging of isometries of the associated hyper-Kählerian target spaces and present the resulting gauge-covariant supersymmetric action functional. e-mail address: [email protected] e-mail address: [email protected]
متن کاملThe Geometry of Supersymmetric Σ-models
We review non-linear σ-models with (2,1) and (2,2) supersymmetry. We focus on off-shell closure of the supersymmetry algebra and give a complete list of (2, 2) superfields. We provide evidence to support the conjecture that all N = (2, 2) non-linear σ-models can be described by these fields. This in its turn leads to interesting consequences about the geometry of the target manifolds. One immed...
متن کاملGeometry and Duality in Supersymmetric Σ - Models
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...
