Probing atom-surface interactions by diffraction of Bose-Einstein condensates
Helmar Bender, Christian Stehle, Claus Zimmermann +5
In this article we analyze the Casimir-Polder interaction of atoms with a solid grating and an additional repulsive interaction between the atoms and the grating in the presence of…
The role of Mie scattering in the seeding of matter-wave superradiance
Romain Bachelard, Helmar Bender, Philippe W. Courteille +4
Matter-wave superradiance is based on the interplay between ultracold atoms coherently organized in momentum space and a backscattered wave. Here, we show that this mechanism may b…
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…
