Nonlinear Oscillator Floquet Stability Bifurcation
font style='font-size:12px;'>
2015/8/27
We investigate the existence and stability of the in-phase and out-of-phase modes for parameters ? > 0 and k > 0. To this end we use Floquet theory and numerical integration. Surprisingly, our results...

Mesoscopic and macroscopic system quantum dynamics coupling model the oscillator
font style='font-size:12px;'>
2014/12/22
The quantum dynamics of mesoscopic or macroscopic systems is always complicated by their coupling to many `environmental' modes. At low T these environmental effects are dominated by localized modes, ...
