A Weyl function approach to matter-wave coherence and Talbot-Lau effects
Saijun Wu, Pierre S. Striehl, Mara G. Prentiss
Weyl functions conveniently describe the evolution of wave coherences in periodic or quadratic potentials. In this work we use Weyl functions to study the ``Talbot-Lau effect'' in…

Bidirectional propagation of cold atoms in a "stadium" shaped magnetic guide
Saijun Wu, Wilbert Rooijakkers, Pierre Striehl +1
We demonstrate the bi-directional propagation of more than 10 7 atoms (87 Rb) around a "stadium" shaped magnetic ring that encloses an area of 10.9 cm 2, with a flux density exceed…

Observation of Caustics in the Trajectories of Cold Atoms in a Linear Magnetic Potential
Wilbert Rooijakkers, Saijun Wu, Pierre Striehl +2
We have studied the spatial and temporal dynamics of a cold atom cloud in the conservative force field of a ferromagnetic guide, after laser cooling has been switched off suddenly.…
