Modulated Electromechanics: Large Enhancements of Nonlinearities



Raymond W. Simmonds, Jie-Qiao Liao, Kurt Jacobs, Franco Nori


It is well-known that the nonlinear coupling between a mechanical oscillator and a superconducting oscillator or optical cavity can be used to generate a Kerr-nonlinearity for the cavity mode. We show that the strength of this Kerr-nonlinearity, as well as the e ect of the photon-pressure force can be enormously increased by modulating the strength of the nonlinear coupling. We present an electromechanical circuit in which this enhancement can be readily realized.
