Scattering matrix for current-current deformations of the (2,2s+1) RSOS models
Y. Pugai, D. Shabetnik
We study (2,2s+1) RSOS lattice models deformed by the current-current operator. Solving the deformed Bethe ansatz equations for the model in the regime III we find explicit express…
Lattice models, deformed Virasoro algebra and reduction equation
Michael Lashkevich, Yaroslav Pugai, Jun'ichi Shiraishi +1
We study the fused currents of the deformed Virasoro algebra (DVA). By constructing a homotopy operator we show that for special values of the parameter of the algebra fused curren…
The complex sinh-Gordon model: form factors of descendant operators and current-current perturbations
Michael Lashkevich, Yaroslav Pugai
We study quasilocal operators in the quantum complex sinh-Gordon theory in the form factor approach. The free field procedure for descendant operators is developed by introducing t…
Algebraic approach to form factors in the complex sinh-Gordon theory
Michael Lashkevich, Yaroslav Pugai
We study form factors of the quantum complex sinh-Gordon theory in the algebraic approach. In the case of exponential fields the form factors can be obtained from the known form fa…
Note on four-particle form factors of operators in sinh-Gordon model
Michael Lashkevich, Yaroslav Pugai
The diagonal matrix elements between two-particle states in the sinh-Gordon model are computed analytically for all integers . Th…
Form factors of descendant operators: Resonance identities in the sinh-Gordon model
Michael Lashkevich, Yaroslav Pugai
We study the space of local operators in the sinh-Gordon model in the framework of the bootstrap form factor approach. Our final goal is to identify the operators obtained by solvi…
