Investigation of the energy operator spectrum for a two-magnon system in a one-dimensional anisotropic heisenberg ferromagnet with second neighbor interactions

  • S. M. Tashpulatov


We consider a physical system of two magnons in an anisotropic one-dimensional Heisenberg ferromagnet with interactions up to the second neighbor. We study the spectrum and bound states of the two-magnon Hamiltonian. We find that under certain conditions, the spectrum differs from that of the isotropic Hamiltonian by one extra or one missing bound state.
