Abstract

A basis of states which are dressed by the interaction between three, largely populated, modes of Bogoliubov quasiparticles in a Bose-Einstein condensate at zero temperature is introduced. Using this basis of quantum states the time evolution of the system, which exhibits nonlinear oscillations between the different momentum modes is calculated. It is shown that, due to relative number squeezing, the variance in the number difference between the two low momentum mode remains constant.
