Engineering transport by concatenated maps
T. Schell, M. Sadgrove, K. Nakagawa +1
We present a generalized kick rotor model in which the phase of the kick can vary from kick to kick. This additional freedom allows one to control the transport in phase space. For…
Resonant driving of a nonlinear Hamiltonian system
Carlo Palmisano, Gianpiero Gervino, Massimo Balma +2
As a proof of principle, we show how a classical nonlinear Hamiltonian system can be driven resonantly over reasonably long times by appropriately shaped pulses. To keep the parame…
Nonlinear dynamics of two coupled nano-electromechanical resonators
L. Chotorlishvili, A. Ugulava, G. Mchedlishvili +3
As a model of coupled nano-electromechanical resonantors we study two nonlinear driven oscillators with an arbitrary coupling strength between them. Analytical expressions are deri…
Resonance-assisted decay of nondispersive wave packets
Sandro Wimberger, Peter Schlagheck, Christopher Eltschka +1
We present a quantitative semiclassical theory for the decay of nondispersive electronic wave packets in driven, ionizing Rydberg systems. Statistically robust quantities are extra…
Can quantum fractal fluctuations be observed in an atom-optics kicked rotor experiment?
Andrea Tomadin, Riccardo Mannella, Sandro Wimberger
We investigate the parametric fluctuations in the quantum survival probability of an open version of the delta-kicked rotor model in the deep quantum regime. Spectral arguments [Gu…
Delocalized and Resonant Quantum Transport in Nonlinear Generalizations of the Kicked Rotor Model
Laura Rebuzzini, Sandro Wimberger, Roberto Artuso
We analyze the effects of a nonlinear cubic perturbation on the delta-Kicked Rotor. We consider two different models, in which the nonlinear term acts either in the position or in…
