Semiclassical dynamics of nanoelectromechanical systems

Dynamics-enabled Nanoelectromechanical Systems (nems) Oscillators

Nonlinear semiclassical dynamics of open systems.

A semiclassical approximation for an evolving density operator, driven by a 'closed' Hamiltonian and 'open' Markovian Lindblad operators, is reviewed. The theory is based on the chord function, i.e. the Fourier transform of the Wigner function. It reduces to an exact solution of the Lindblad master equation if the Hamiltonian is a quadratic function and the Lindblad operators are linear functio...

REVIEW ARTICLE Nanoelectromechanical systems

Nanoelectromechanical systems sNEMSd are drawing interest from both technical and scientific communities. These are electromechanical systems, much like microelectromechanical systems, mostly operated in their resonant modes with dimensions in the deep submicron. In this size regime, they come with extremely high fundamental resonance frequencies, diminished active masses, and tolerable force c...

24 Nanoelectromechanical Systems – Experiments andModeling

Nanoelectromechanical systems (NEMS) aremade of electromechanical devices that have critical dimensions from hundreds down to a few nanometers. By exploring nanoscale effects, NEMS present interesting and unique characteristics, which deviate greatly from their predecessor microelectromechanical systems (MEMS). For instance, NEMS-based devices can have fundamental frequencies in the microwave r...
