Kicked-rotor quantum resonances in position space: Application to situations of experimental interest
M. Lepers, V. Zehnlé, J. -C. Garreau
In this work we apply the formalism developed in [M. Lepers \emph{et al}., Phys. Rev. A \textbf{77}, 043628 (2008)] to different initial conditions corresponding to systems usually…
Tracking quasi-classical chaos in ultracold boson gases
Maxence Lepers, Véronique Zehnlé, Jean Claude Garreau
We study the dynamics of a ultra-cold boson gas in a lattice submitted to a constant force. We track the route of the system towards chaos created by the many-body-induced nonlinea…
Kicked rotor quantum resonances in position space
Maxence Lepers, Véronique Zehnlé, Jean Claude Garreau
We present an approach of the kicked rotor quantum resonances in position-space, based on its analogy with the optical Talbot effect. This approach leads to a very simple picture o…
Atomic motion in tilted optical lattices
Quentin Thommen, Jean Claude Garreau, Veronique Zehnle
This paper presents a formalism describing the dynamics of a quantum particle in a one-dimensional, time-dependent, tilted lattice. The formalism uses the Wannier-Stark states, whi…
Classical chaos with Bose-Einstein condensates in tilted optical lattices
Quentin Thommen, Jean Claude Garreau, Véronique Zehnlé
A widely accepted definition of ``quantum chaos'' is ``the behavior of a quantum system whose \emph{classical} \emph{limit is chaotic}''. The dynamics of quantum-chaotic systems is…
Wavepacket reconstruction via local dynamics in a parabolic lattice
Quentin Thommen, Veronique Zehnle, Jean Claude Garreau
We study the dynamics of a wavepacket in a potential formed by the sum of a periodic lattice and of a parabolic potential. The dynamics of the wavepacket is essentially a superposi…
