We show the formation of ultraslow optical solitons in a lifetime broadened four-state atomic
medium under Raman excitation. With appropriate conditions we demonstrate, both …

We have performed a number of experiments with a Bose-Einstein condensate (BEC) in a
one-dimensional optical lattice. Making use of the small momentum spread of a BEC and …

We study the horizontal transport of ultracold atoms over macroscopic distances of up to 20
cm with a moving 1D optical lattice. By using an optical Bessel beam to form the optical …

We theoretically investigate the transmission dynamics of coherent matter wave pulses
across finite optical lattices in both the linear and the nonlinear regimes. The shape and the …

We study the creation of stationary cold molecules by rapid deceleration of supersonically
cooled molecules in a high-intensity pulsed optical lattice. Using the heavy molecule I 2 as …

We investigate the time evolution of a Bose-Einstein condensate in a periodic optical
potential. Using an effective mass formalism, we study the equation of motion for the …

Motivated by recent results using shaken optical lattices to perform atom interferometry, we
explore the splitting of an atom cloud trapped in a phase-modulated ('shaken') optical lattice …

Die heutige Generation atomarer Inertialsensoren arbeitet typischerweise mit
lasergekühlten Atomen, die aus einer optischen Melasse fallen gelassen oder gestartet …

We demonstrate theoretically the use of genetic-learning algorithms to coherently control the
dynamics of a Bose-Einstein condensate. We consider specifically the situation of a …

We study a Bose-Einstein condensate in a one-dimensional accelerated optical lattice using
the mean-field version of the Bose-Hubbard model. Reminiscent of recent experiments [M …
