چکیده انگلیسی
Starting from critical RSOS lattice models with appropriate inhomogeneities, we derive two component nonlinear integral equations to describe the finite volume ground state energy of the massive Ïid,id,adj perturbation of the SU(2)kÃSU(2)kâ²/SU(2)k+kâ² coset models. When kâ²ââ while the value of k is fixed, the equations correspond to the current-current perturbation of the SU(2)k WZW model. Then modifying one of the kernel functions of these equations, we propose two component nonlinear integral equations for the fractional supersymmetric sine-Gordon models. The lattice versions of our equations describe the finite size effects in the corresponding lattice models, namely in the critical RSOS(k,q) models, in the isotropic higher-spin vertex models, and in the anisotropic higher-spin vertex models. Numerical and analytical checks are also performed to confirm the correctness of our equations. These type of equations make it easier to treat the excited state problem.
