Unstable Semiclassical Trajectories in Tunneling
D. G. Levkov, A. G. Panin, S. M. Sibiryakov
Some tunneling phenomena are described, in the semiclassical approximation, by unstable complex trajectories. We develop a systematic procedure to stabilize the trajectories and to…
On the over-barrier reflection in quantum mechanics with multiple degrees of freedom
D. G. Levkov, A. G. Panin, S. M. Sibiryakov
We present an analytic example of two dimensional quantum mechanical system, where the exponential suppression of the probability of over-barrier reflection changes non-monotonical…
Complex trajectories in chaotic dynamical tunneling
D. G. Levkov, A. G. Panin, S. M. Sibiryakov
We develop the semiclassical method of complex trajectories in application to chaotic dynamical tunneling. First, we suggest a systematic numerical technique for obtaining complex…
