Calculation of mode coupling for quadrupole excitations in a Bose-Einstein condenstate
A simple model describing the nonlinear coupling of quasiparticle amplitudes of two modes is derived. The model, in particular, can be used to study squeezing effects that are directly related to the matrix element governing the coupling process. This paper demonstrates how to calculate this matrix...
