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 thermal equilibration from equipartition
A. V. Ponomarev, S. Denisov, J. Gemmer +1
The problem of mutual equilibration between two finite, identical quantum systems, A and B, prepared initially at different temperatures is elucidated. We show that the process of…
Mapping the Arnold web with a GPU-supercomputer
A. Seibert, S. Denisov, A. V. Ponomarev +1
The Arnold diffusion constitutes a dynamical phenomenon which may occur in the phase space of a non-integrable Hamiltonian system whenever the number of the system degrees of freed…
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…
Oscillons: an encounter with dynamical chaos in 1953?
S. Denisov, A. V. Ponomarev
We present evidences that Ben F. Laposky (1914-2000) might have been the first person who created a family of nonlinear analog circuits that allowed him to observe chaotic attracto…
Thermal equilibration between two quantum systems
Alexey V. Ponomarev, Sergey Denisov, Peter Hänggi
Two identical finite quantum systems prepared initially at different temperatures, isolated from the environment, and subsequently brought into contact are demonstrated to relax to…
