Excitation and damping of collective modes of a Bose-Einstein condensate in a one-dimensional lattice
O. Morsch, J. H. Müller, D. Ciampini +5
The mode structure of a Bose-Einstein condensate non-adiabatically loaded into a one-dimensional optical lattice is studied by analyzing the visibility of the interference pattern…
Free expansion of a Bose-Einstein condensate in a 1D optical lattice
O. Morsch, M. Cristiani, J. H. Müller +2
We have experimentally investigated the free expansion of a Bose-Einstein condensate in an array of two-dimensional traps created by a one-dimensional optical lattice. If the conde…
Experimental properties of Bose-Einstein condensates in 1D optical lattices: Bloch oscillations, Landau-Zener tunneling and mean-field effects
M. Cristiani, O. Morsch, J. H. Müller +2
We report experimental results on the properties of Bose-Einstein condensates in 1D optical lattices. By accelerating the lattice, we observed Bloch oscillations of the condensate…
Bloch oscillations and mean-field effects of Bose-Einstein condensates in 1-D optical lattices
O. Morsch, J. H. Müller, M. Cristiani +2
We have loaded Bose-Einstein condensates into one-dimensional, off-resonant optical lattices and accelerated them by chirping the frequency difference between the two lattice beams…
Bose-Einstein condensation of rubidium atoms in a triaxial TOP-trap
J. H. Müller, D. Ciampini, O. Morsch +5
We report the results of experiments with Bose-Einstein condensates of rubidium atoms in a triaxial TOP-trap, presenting measurements of the condensate fraction and the free expans…
