Nonlinear Floquet dynamics of spinor condensates in an optical cavity: Cavity-amplified parametric resonance
Zheng-Chun Li, Qi-Hui Jiang, Zhihao Lan +2 more
We investigate the Floquet dynamics of a cavity-spinor Bose-Einstein condensate coupling system via periodic modulation of the cavity pump laser. Parametric resonances are predicted, and we show that due to cavity feedback-induced nonlinearity, the spin oscillation can be amplified to all orders of resonance, thus facilitating its detection. Real-time observation of Floquet dynamics via cavity output is also discussed.
