Magnon-magnon interaction in a square lattice
V. K. Tkachenko
Abstract:
A square lattice of spins 1/2 with exchange interaction between nearest neighbors is studied. The eigenfunctions of two magnons describing magnon-magnon scattering
are found. Conditions of singular scattering are given. The magnon-magnon
interaction cannot be neglected even in the long-wave limit.
