Diffusion-induced bistability of driven nanomechanical resonators.

We study nanomechanical resonators with frequency fluctuations due to diffusion of absorbed particles. The diffusion depends on the vibration amplitude through inertial effect. We find that, if the diffusion coefficient D is sufficiently large, the resonator response to periodic driving displays bistability. The lifetime of the coexisting vibrational states exponentially increases with increasi...

Diffusion-induced dephasing in nanomechanical resonators

We study resonant response of an underdamped nanomechanical resonator with fluctuating frequency. The fluctuations are due to diffusion of molecules or microparticles along the resonator. They lead to broadening and change of shape of the oscillator spectrum. The spectrum is found for the diffusion confined to a small part of the resonator and where it occurs along the whole nanobeam. The analy...

Damping of nanomechanical resonators.

We study the transverse oscillatory modes of nanomechanical silicon nitride strings under high tensile stress as a function of geometry and mode index m≤9. Reproducing all observed resonance frequencies with classical elastic theory we extract the relevant elastic constants. Based on the oscillatory local strain we successfully predict the observed mode-dependent damping with a single frequency...

Quantized nanomechanical resonators

are well suited to such explorations. Their dimensions not only make them susceptible to local forces, but also make it possible to integrate and tightly couple them to a variety of interesting electronic structures, such as solid-state twolevel systems (quantum bits, or qubits), that exhibit quantum mechanical coherence. In fact, the most-studied systems, nanoresonators coupled to various supe...

Particle number scaling for diffusion-induced dissipation in graphene and carbon nanotube nanomechanical resonators

When a contaminant diffuses on the surface of a nanomechanical resonator, the motions of the two become correlated. Despite being a high-order effect in the resonator-particle coupling, such correlations affect the system dynamics by inducing dissipation of the resonator energy. Here, we consider this diffusion-induced dissipation in the cases of multiple particles adsorbed on carbon nanotube a...
