We systematically investigate the nonlinearity of librational and translational modes, and present a theoretical scheme for quantum ground state cooling of both librational and translational modes of an optically levitated nonspherical nanoparticle via cavity mode. By expanding the trapping potential to the fourth order of both the translational and librational freedom degrees, we obtain the inherent nonlinearity of them and their nonlinear coupling. Through stability analysis, bi‐ and multistability are presented in this system, when either the librational or the translational drive is red‐detuning. The system will be stabilized if and only if these two drives are both blue‐detuning. In order to obtain the quantum ground states of the motional modes of ellipsoidal nanoparticle, a cavity mode is utilized to cool the librational and translational modes. By optimizing the frequencies and amplitudes of drives and residual air pressure, the quantum ground states of the librational and translational modes can be realized at the same time.

Tunable optomechanically induced transparency (OMIT) with an induced electric field (IEF) in a quadratic-coupling optomechanical system is theoretically investigated. The system transmission rate under different controlling parameters has been discussed. It is revealed that both phase and group delay of the probe field can be adjusted by the IEF and pump field. Such a system may be used in tunable optical buffer, IEF detector, modulator or other optical devices.

We theoretically investigate the optical second-order sideband generation (OSSG) in an optical parity-time (PT) symmetric system, which consists of a passive cavity trapping the atomic ensemble and an active cavity. Compared with the double-passive system, it is found that near the exceptional point (EP), the efficiency of the OSSG increases sharply not only for the blue probepump detuning resonant case but also for the red one. Using experimentally achievable parameters, we study the effect of the atomic ensemble on the efficiency of the OSSG in the PT-symmetric system. The numerical results show that the efficiency of the OSSG is 30% higher than that of the first-order sideband, which is realized easily by simultaneously modulating the atom-cavity coupling strength and detuning. Moreover, the efficiency of the OSSG can also be tuned effectively by the pump power, and the efficiency is robust when the pump power is strong enough. This study may have some guidance for modulating the nonlinear optical properties and controlling light propagation, which may stimulate further applications in optical communications. second-order sideband effects, parity-time symmetry, optomechanical system
