Superconformal Symmetries and Models
We discuss the following aspects of two-dimensional N = 2 supersymmetric theories defined on compact super Riemann surfaces: parametrization of (2, 0) and (2, 2) superconformal structures in terms of Beltrami coefficients and formulation of superconformal models on such surfaces (invariant actions, anomalies and compensating actions, Ward identities).
متن کاملGalilean noncommutative gauge theory: symmetries & vortices
Noncommutative Chern-Simons gauge theory coupled to nonrelativistic scalars or spinors is shown to admit the “exotic” two-parameter-centrally extended Galilean symmetry, realized in a unique way consistent with the Seiberg-Witten map. Nontopological spinor vortices and topological external-field vortices are constructed by reducing the problem to previously solved self-dual equations.
متن کاملStudy on Deformed Galilean Symmetries in Noncommutative Phase Space
The deformed Galilean generators are constructed on a space where both position and momentum coordinates are noncommutating operators. A dynamical model invariant under deformed phase space transformations is constructed. The Dirac brackets of this model reproduce the original non-commutative algebra. Also, the deformed generators are abstracted from this model in a consistent manner. Finally, ...
متن کاملv 1 9 J un 1 99 2 EXTENDED SUPERCONFORMAL GALILEAN SYMMETRY IN CHERN - SIMONS MATTER SYSTEMS
We study the nonrelativistic limit of the N = 2 supersymmetric Chern-Simons matter system. We show that in addition to Galilean invariance the model admits a set of symmetries generated by fermionic charges, which can be interpreted as an extended Galilean supersymmetry. The system also possesses a hidden conformal invariance and then the full group of symmetries is the extended superconformal ...
متن کاملAcceleration-extended Galilean Symmetries with Central Charges and Their Dynamical Realizations
We add to Galilean symmetries the transformations describing constant accelerations. The corresponding extended Galilean algebra allows, in any dimension D = d + 1, the introduction of one central charge c while in D = 2 + 1 we can have three such charges: c, θ and θ. We present nonrelativistic classical mechanics models, with higher order time derivatives and show that they give dynamical real...
