Basins of Attraction of a Nonlinear Nanomechanical Resonator

Basins of Attraction of a Nonlinear Nanomechanical Resonator

We present an experiment that systematically probes the basins of attraction of two fixed points of a nonlinear nanomechanical resonator and maps them out with high resolution. We observe a separatrix which progressively alters shape for varying drive strength and changes the relative areas of the two basins of attraction. …
