Dynamic Quantum Tunneling in Mesoscopic Driven Duffing Oscillators

preprint2011arXivOpen access

Abstract

We investigate the dynamic quantum tunneling between two attractors of a mesoscopic driven Duffing oscillator. We find that, in addition to inducing remarkable quantum shift of the bifurcation point, the mesoscopic nature also results in a perfect linear scaling behavior for the tunneling rate with the driving distance to the shifted bifurcation point.
