Role of dimensionality in spontaneous magnon decay: Easy-plane ferromagnet

We calculate the magnon lifetime in an easyplane ferromagnet on a tetragonal lattice in a transverse magnetic field. At zero temperature magnons are unstable with respect to spontaneous decay into two other magnons. Varying the ratio of intrachain to interchain exchanges in this model, we consider t...
