A method for solving a continuous isotropic Heisenberg spin model endowed with SU(1, 1) symmetry is presented. Exact analytical solutions are obtained together with the hamiltonian and the magnetization under periodic boundary conditions for the spin fields.

A method for solving a continuous isotropic Heisenberg spin model endowed with SU(1, 1) symmetry is presented. Exact analytical solutions are obtained together with the hamiltonian and the magnetization under periodic boundary conditions for the spin fields.File in questo prodotto:
