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…
Klein-Tunneling of a Quasirelativistic Bose-Einstein Condensate in an Optical Lattice
Tobias Salger, Sebastian Kling, Christopher Grossert +1
Optical lattices have proven to be powerful systems for quantum simulations of solid state physics effects. Here we report a proof-of-principle experiment simulating effects predic…
On the effective Dirac dynamics of ultracold atoms in bichromatic optical lattices
D. Witthaut, T. Salger, S. Kling +2
We study the dynamics of ultracold atoms in tailored bichromatic optical lattices. By tuning the lattice parameters, one can readily engineer the band structure and realize a Dirac…
Atomic Bloch-Zener Oscillations and Stückelberg Interferometry in Optical Lattices
Sebastian Kling, Tobias Salger, Christopher Grossert +1
We report on experiments investigating quantum transport and band interferometry of an atomic Bose-Einstein condensate in an optical lattice with a two-band miniband structure, rea…
Directed Transport of Atoms in a Hamiltonian Quantum Ratchet
Tobias Salger, Sebastian Kling, Tim Hecking +3
We demonstrate the operation of a quantum ratchet in the absence of dissipative processes within the observation time (Hamiltonian regime). An atomic rubidium Bose-Einstein condens…
Bloch oscillations of atoms in an optical multiphoton potential
Tobias Salger, Gunnar Ritt, Carsten Geckeler +2
We report on experiments studying transport properties of an atomic Bose-Einstein condensate in an optical lattice of spatial period , where is an integer, realized with…
Dynamical Properties of a Rotating Bose-Einstein Condensate
Sebastian Kling, Axel Pelster
Within a variational approach to solve the Gross-Pitaevskii equation we investigate dynamical properties of a rotating Bose-Einstein condensate which is confined in an anharmonic t…
Atomic Landau-Zener tunneling in Fourier-synthesized optical lattices
Tobias Salger, Carsten Geckeler, Sebastian Kling +1
We report on an experimental study of quantum transport of atoms in variable periodic optical potentials. The band structure of both ratchet-type asymmetric and symmetric lattice p…
Thermodynamical Properties of a Rotating Ideal Bose Gas
Sebastian Kling, Axel Pelster
In a recent experiment, a Bose-Einstein condensate was trapped in an anharmonic potential which is well approximated by a harmonic and a quartic part. The condensate was set into s…
