Two oscillators in a dissipative bath
Two forms of dissipation are applied to a system of two coupled harmonic oscillators. Result¬ing quantum master equations are studied with the help of quantum characteristic functions. The effects of dissipation on quantum ...
Energy dissipation mechanisms in carbon nanotube oscillators
Energy transfer from the translational degrees of freedom to phonon modes is studied for isolated systems of two coaxial carbon nanotubes, which may serve as a nearly frictionless nano-oscillator. It is found that for ...
