Beyond the Dicke Quantum Phase Transition with a Bose-Einstein Condensate in an Optical Ring Resonator
D. Schmidt, H. Tomczyk, S. Slama +1
We experimentally investigate the dynamical instability of a Bose Einstein condensate in an optical ring resonator for various cavity detuning and pump powers. The resulting phase…
Observation of cooperative Mie scattering from an ultracold atomic cloud
H. Bender, C. Stehle, S. Slama +4
Scattering of light at a distribution of scatterers is an intrinsically cooperative process, which means that the scattering rate and the angular distribution of the scattered ligh…
Cooperative Scattering by Cold Atoms
S. Bux, E. Lucioni, H. Bender +8
We have studied the interplay between disorder and cooperative scattering for single scattering limit in the presence of a driving laser. Analytical results have been derived and w…
Direct Measurement of intermediate-range Casimir-Polder potentials
Helmar Bender, Philippe W. Courteille, Carsten Marzok +2
We present the first direct measurements of Casimir-Polder forces between solid surfaces and atomic gases in the transition regime between the electrostatic short-distance and the…
Meissner effect in superconducting microtraps
D. Cano, B. Kasch, H. Hattermann +4
We report on the realization and characterization of a magnetic microtrap for ultra cold atoms near a straight superconducting Nb wire with circular cross section. The trapped atom…
Rubidium Spectroscopy at 778-780 nm with a Distributed Feedback Laser Diode
S. Kraft, A. Deninger, Ch. Truck +3
We have performed high resolution spectroscopy of rubidium with a single mode continuous wave distributed feedback (DFB) laser diode. The saturation spectrum of the D_2-line of 85R…
