Tuning the mobility of a driven Bose-Einstein condensate via diabatic Floquet bands
T. Salger, S. Kling, S. Denisov +3
We study the response of ultracold atoms to a weak force in the presence of a temporally strongly modulated optical lattice potential. It is experimentally demonstrated that the st…

Quantum ratchet transport with minimal dispersion rate
Fei Zhan, S. Denisov, A. V. Ponomarev +1
We analyze the performance of quantum ratchets by considering the dynamics of an initially localized wave packet loaded into a flashing periodic potential. The directed center-of-m…

Levy distribution in many-particle quantum systems
A. V. Ponomarev, S. Denisov, P. Hanggi
Levy distribution, previously used to describe complex behavior of classical systems, is shown to characterize that of quantum many-body systems. Using two complimentary approaches…
