Nonlinearity induced destruction of resonant tunneling in the Wannier-Stark problem
Sandro Wimberger, Riccardo Mannella, Oliver Morsch +3
We present detailed numerical results on the dynamics of a Bose-Einstein condensate in a tilted periodic optical lattice over many Bloch periods. We show that an increasing atom-at…
The role of quasi-momentum in the resonant dynamics of the atom-optics kicked rotor
Sandro Wimberger, Mark Sadgrove
We examine the effect of the initial atomic momentum distribution on the dynamics of the atom-optical realisation of the quantum kicked rotor. The atoms are kicked by a pulsed opti…
Experimental verification of a one-parameter scaling law for the quantum and "classical" resonances of the atom-optics kicked rotor
Sandro Wimberger, Mark Sadgrove, Scott Parkins +1
We present experimental measurements of the mean energy in the vicinity of the first and second quantum resonances of the atom optics kicked rotor for a number of different experim…
Resonant nonlinear quantum transport for a periodically kicked Bose condensate
Sandro Wimberger, Riccardo Mannella, Oliver Morsch +1
Our realistic numerical results show that the fundamental and higher-order quantum resonances of the delta-kicked rotor are observable in state-of-the-art experiments with a Bose c…
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…
A classical scaling theory of quantum resonances
Sandro Wimberger, Italo Guarneri, Shmuel Fishman
The quantum resonances occurring with delta-kicked particles are studied with the help of a fictitious classical limit, establishing a direct correspondence between the nearly reso…
