Optically levitated nanoparticle as a model system for stochastic bistable dynamics.

摘要: Nano-mechanical resonators have gained an increasing importance in nanotechnology owing to their contributions both fundamental and applied science. Yet, small dimensions mass raises some challenges as dynamics gets dominated by nonlinearities that degrade performance, for instance sensing applications. Here, we report on the precise control of nonlinear stochastic bistable a levitated nanoparticle high vacuum. We demonstrate how it can lead efficient signal amplification schemes, including resonance. This work contributes showing use nanoparticles model system dynamics, with applications wide variety fields.
