Nonlinearity induced destruction of resonant tunneling in the Wannier-Stark problem
Sandro Wimberger, Riccardo Mannella, Oliver Morsch +3
We present detailed numerical results on the dynamics of a Bose-Einstein condensate in a tilted periodic optical lattice over many Bloch periods. We show that an increasing atom-at…
Two photon ionization of condensate atoms
M. Anderlini, E. Arimondo
The efficient photoionization of a Bose-Einstein condensate requires the creation of ions with the smallest possible transfer of atoms from the condensate into the thermal phase. T…
Resonant nonlinear quantum transport for a periodically kicked Bose condensate
Sandro Wimberger, Riccardo Mannella, Oliver Morsch +1
Our realistic numerical results show that the fundamental and higher-order quantum resonances of the delta-kicked rotor are observable in state-of-the-art experiments with a Bose c…
Manipulation of ultracold atomic mixtures using microwave techniques
D. Ciampini, E. Courtade, C. Sias +5
We used microwave radiation to evaporatively cool a mixture of of 133Cs and 87Rb atoms in a magnetic trap. A mixture composed of an equal number (around 10^4) of Rb and Cs atoms in…
Hitting a BEC with a comb: Evolution of interference patterns inside a magnetic trap
J. H. Müller, O. Morsch, M. Cristiani +2
We study the evolution inside a harmonic trap of Bose-Einstein condensates released from the periodic potential of an optical lattice. After a time-of-flight, harmonic motion of th…
Ultracold atoms and Bose-Einstein condensates in optical lattices
O. Morsch, E. Arimondo
For ultracold and Bose-condensed atoms contained in periodic optical potential wells the quantized nature of their motion is clearly visible. The motion of the atomic wavepacket ca…
