Monte Carlo study of exact S-matrix duality in nonsimply laced affine Toda theories.
The (g (1) 2 , d (3) 4 ) pair of non simply laced affine Toda theories is studied from the point of view of non perturbative duality. The classical spectrum of each member is composed of two massive scalar particles. The exact S-matrix prediction for the dual behaviour of the coupling dependent mass ratio is found to be in strong agreement with Monte Carlo data. keywords: Affine Toda theories, ...
متن کاملExact quantum S-matrices for solitons in simply-laced affine Toda field theories
We obtain exact solutions to the quantum S-matrices for solitons in simply-laced affine Toda field theories, except for certain factors of simple type which remain undetermined in some cases. These are found by postulating solutions which are consistent with the semi-classical limit, h̄ → 0, and the known time delays for a classical two soliton interaction. This is done by a ‘q-deformation’ proc...
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 کاملS-matrices of non-simply laced affine Toda theories by folding
The exact factorisable quantum S-matrices are known for simply laced as well as non-simply laced affine Toda field theories. Non-simply laced theories are obtained from the affine Toda theories based on simply laced algebras by folding the corresponding Dynkin diagrams. The same process, called classical ‘reduction’, provides solutions of a non-simply laced theory from the classical solutions w...
متن کاملS-matrices and bi-linear sum rules of conserved charges in affine Toda field theories
The exact quantum S-matrices and conserved charges are known for affine Toda field theories(ATFTs). In this note we report on a new type of bi-linear sum rules of conserved quantities derived from these exact S matrices. They exist when there is a multiplicative identity among S-matrices of a particular ATFT. Our results are valid for simply laced as well as non-simply laced ATFTs. We also pres...
