Schematic diagram of the proposed hybrid optomechanical system. The Fabry–Pérot cavity contains a movable mirror, which interacts with both the cavity field via the radiation pressure and the nearby fixed gold-coated nanosphere via the Casimir force. In addition, the system is simultaneously driven by a strong control field with amplitude εL and a weak probe field with amplitude εp. εout is the amplitude of the output field, and x describes the deviation of the mirror from its equilibrium position.
