Abstract
We study quantum dynamics of three dressed Bose-Einstein condensates in a h igh-Q cavity. The quasiparticle excitation spectrum of this system is found numerically. The stability of the quasiparticle excitation is analyzed. It is shown that there exist instabilities in the excitation spectrum.
