A semiclassical theory of chaotic atomic transport in a one-dimensional nondissipative
optical lattice, when the standing-wave field and center-of-mass motion are treated …

We study experimentally and theoretically a beam splitter setup for guided atomic matter
waves. The matter wave is a guided atom laser that can be tuned from quasimonomode to a …

Cold atoms in optical potentials provide an ideal test bed to explore quantum nonlinear
dynamics. Atoms are prepared in a magneto-optic trap or as a dilute Bose–Einstein …

We formulate a general method for the study of semiclassical-like dynamics in stable regions
of a mixed phase space, in order to theoretically study the dynamics of quantum accelerator …

Cold rubidium atoms are subjected to an amplitude-modulated far-detuned standing wave of
light to form a quantum-driven pendulum. Here we discuss the dynamics of these atoms …

En attendant de parvenir à construire un ordinateur quantique universel, les physiciens se
sont attelés à développer des simulateurs quantiques: un système capable d'émuler des …

This thesis presents an account of experimental and numerical investigations of two
quantum systems whose respective classical analogues are chaotic. These are the delta …

In this paper an effective quantum particle beam-splitter in the momentum space is realized
in the frame of open-loop control scheme. We demonstrate for small interaction time that the …

Summary form only given. We represent the first experiment evidence of dynamic tunneling
of ultra-cold rubidium atoms. Rather then tunneling through a potential well, an atom tunnels …
