Classical versus Quantum Symmetries for Toda Theories with a Nontrivial Boundary Perturbation
In this paper we present a detailed study of the quantum conservation laws for Toda field theories defined on the half plane in the presence of a boundary perturbation. We show that total derivative terms added to the currents, while irrelevant at the classical level, become important at the quantum level and in general modify significantly the quantum boundary conservation. We consider the fir...
متن کاملIfum 435/ft Quantum Symmetries in Supersymmetric Toda Theories
We consider two–dimensional supersymmetric Toda theories based on the Lie superalgebrasA(n, n), D(n+1, n) and B(n, n) which admit a fermionic set of simple roots and a fermionic untwisted affine extension. In particular, we concentrate on two simple examples, the B(1, 1) and A(1, 1) theories. Both in the conformal and massive case we address the issue of quantum integrability by constructing th...
متن کاملQuantum Boundary Currents for Nonsimply–laced Toda Theories
We study the quantum integrability of nonsimply–laced affine Toda theories defined on the half–plane and explicitly construct the first nontrivial higher–spin charges in specific examples. We find that, in contradistinction to the classical case, addition of total derivative terms to the ”bulk” current plays a relevant role for the quantum boundary conservation.

متن کاملaffine Toda field theories with integrable boundary conditions revisited
Generic classically integrable boundary conditions for the A (1) n affine Toda field theories (ATFT) are investigated. The present analysis relies primarily on the underlying algebra, defined by the classical version of the reflection equation. We use as a prototype example the first non-trivial model of the hierarchy i.e. the A (1) 2 ATFT, however our results may be generalized for any A (1) n...
