A quantum motor: directed wavepacket motion in an optical lattice
Quentin Thommen, Jean Claude Garreau, Véronique Zehnlé
We propose a method for arbitrary manipulations of a quantum wavepacket in an optical lattice by a suitable modulation of the lattice amplitude. A theoretical model allows to deter…
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…
Theoretical analysis of quantum dynamics in 1D lattices: Wannier-Stark description
Quentin Thommen, Jean Claude Garreau, Veronique Zehnle
This papers presents a formalism describing the dynamics of a quantum particle in a one-dimensional tilted time-dependent lattice. The description uses the Wannier-Stark states, wh…
