Gravity Cutoff in Theories with Large Discrete Symmetries
Gia Dvali, Michele Redi, Sergey Sibiryakov +1
We set an upper bound on the gravitational cutoff in theories with exact quantum numbers of large N periodicity, such as Z_N discrete symmetries. The bound stems from black hole ph…

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…
