Quantum dynamics of instability-induced pulsations of a Bose-Einstein condensate in an optical lattice
Quantum dynamics instability-induced pulsations Bose-Einstein condensate optical lattice
2010/4/13
We study the dynamics of a Bose-Einstein condensate in a one-dimensional optical lattice in the limit of weak atom-atom interactions, including an approximate model for quantum fluctuations. A pulsati...
Quantum and Classical Dynamics of a BEC in a Large-Period Optical Lattice
Quantum and Classical Dynamics BEC Large-Period Optical Lattice
2010/4/8
We experimentally investigate diffraction of a Rb-87 Bose-Einstein condensate from a 1D optical lattice. We use a range of lattice periods and timescales, including those beyond the Raman-Nath limit. ...
