 The study of the optomechanical interaction between a Bose-Einstein condensate and an ultra-hyphen S-standing wave optical resonator with strong cooperative coupling, cavity-dominated scattering, sub-recoil resolution, and a per-cell factor far above unity reveals highly non-linear dynamics with bistability, hysteresis, persistent oscillations, and super-adient backscattering instabilities.
