Realization of a single Josephson junction for Bose-Einstein condensates
Rudolf Gati, Micheal Albiez, Jonas Foelling +2
We report on the realization of a double-well potential for Rubidium-87 Bose-Einstein condensates. The experimental setup allows the investigation of two different dynamical phenom…
Noise Thermometry with Two Weakly Coupled Bose-Einstein Condensates
Rudolf Gati, Boerge Hemmerling, Jonas Foelling +2
Here we report on the experimental investigation of thermally induced fluctuations of the relative phase between two Bose-Einstein condensates which are coupled via tunneling. The…
Direct Observation of Tunneling and Nonlinear Self-Trapping in a single Bosonic Josephson Junction
Michael Albiez, Rudolf Gati, Jonas Foelling +3
We report on the first realization of a single bosonic Josephson junction, implemented by two weakly linked Bose-Einstein condensates in a double-well potential. In order to fully…
Nonlinear Self-Trapping of Matter Waves in Periodic Potentials
Th. Anker, M. Albiez, R. Gati +4
We report the first experimental observation of nonlinear self-trapping of Bose-condensed 87Rb atoms in a one dimensional waveguide with a superimposed deep periodic potential . Th…
Bright gap solitons of atoms with repulsive interaction
B. Eiermann, Th. Anker, M. Albiez +4
We report on the first experimental observation of bright matter-wave solitons for 87Rb atoms with repulsive atom-atom interaction. This counter intuitive situation arises inside a…
Linear and nonlinear dynamics of matter wave packets in periodic potentials
Th. Anker, M. Albiez, B. Eiermann +2
We investigate experimentally and theoretically the nonlinear propagation of 87Rb Bose Einstein condensates in a trap with cylindrical symmetry. An additional weak periodic potenti…
