Conserved Quantities in Noncommutative Principal Chiral Model with Wess-Zumino Term
نویسندگان
چکیده
We construct noncommutative extension of U(N) principal chiral model with Wess-Zumino term and obtain an infinite set of local and non-local conserved quantities for the model using iterative procedure of Brezin et.al [17]. We also present the equivalent description as Lax formalism of the model. We expand the fields perturbatively and derive zerothand first-order equations of motion, zero-curvature condition, iteration method, Lax formalism, local and non-local conserved quantities. PACS: 11.10.Nx, 02.30.Ik

Conserved charges and supersymmetry in principal chiral and WZW models
Conserved and commuting charges are investigated in both bosonic and supersymmetric classical chiral models, with and without Wess-Zumino terms. In the bosonic theories, there are conserved currents based on symmetric invariant tensors of the underlying algebra, and the construction of infinitely many commuting charges, with spins equal to the exponents of the algebra modulo its Coxeter number,...
متن کاملQuantum Mechanically Induced Wess-Zumino Term in the Principal Chiral Model
It is argued that, in the two dimensional principal chiral model, the Wess-Zumino term can be induced quantum mechanically, allowing the model with the critical value of the coupling constant λ = 8π/|k| to turn into the WessZumino-Novikov-Witten model at the quantum level. The Wess-Zumino term emerges from the inequivalent quantizations possible on a sphere hidden in the configuration space of ...

We discuss the ultraviolet properties of bosonic and supersymmetric noncommutative non-linear σ-models in two dimensions, both with and without a Wess-Zumino-Witten There has been a great deal of recent interest in noncommutative (NC) quantum field theories, stimulated by their connection with string theory and M-theory; for a review and comprehensive list of references see Ref.

متن کامل2 00 1 Chern - Simons action in noncommutative space
We derive the noncommutative Chern-Simons action induced by Dirac fermions coupled to a background gauge field, for the fundamental , antifundamental, and the adjoint representation. We discuss properties of the noncommutative Chern-Simons action showing in particular that the Seiberg-Witten formula maps it into the standard commutative Chern-Simons action. Recent results in noncommutative geom...
