Dynamic Quantum Tunneling in Mesoscopic Driven Duffing Oscillators
arXiv:1002.3969 · doi:10.1103/PhysRevE.84.011144
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.
