Properties of a continuous SU(1,1) spin model
No full textA 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
