A hexapole-compensated magneto-optical trap on a mesoscopic atom chip
Stefan Jöllenbeck, Jan Mahnke, Richard Randoll +3
Magneto-optical traps on atom chips are usually restricted to small atomic samples due to a limited capture volume caused primarily by distorted field configurations. Here we prese…
Adiabatic spin cooling using high-spin Fermi gases
M. Colomé-Tatché, C. Klempt, L. Santos +1
Spatial entropy redistribution plays a key role in adiabatic cooling of ultra-cold lattice gases. We show that high-spin fermions with a spatially variable quadratic Zeeman couplin…
Spontaneous breaking of spatial and spin symmetry in spinor condensates
M. Scherer, B. Lücke, G. Gebreyesus +6
Parametric amplification of quantum fluctuations constitutes a fundamental mechanism for spontaneous symmetry breaking. In our experiments, a spinor condensate acts as a parametric…
A slow gravity compensated Atom Laser
G. Kleine Büning, J. Will, W. Ertmer +2
We report on a slow guided atom laser beam outcoupled from a Bose-Einstein condensate of 87Rb atoms in a hybrid trap. The acceleration of the atom laser beam can be controlled by c…
Parametric amplification of matter waves in dipolar spinor Bose-Einstein condensates
F. Deuretzbacher, G. Gebreyesus, O. Topic +6
Spin-changing collisions may lead under proper conditions to the parametric amplification of matter waves in spinor Bose-Einstein condensates. Magnetic dipole-dipole interactions,…
