On the absence of the electrostriction force in dilute clouds of cold atoms
Arnaud Courvoisier, Nir Davidson
The momentum of light in a medium and the mechanisms of momentum transfer between light and dielectrics have long been the topic of controversies and confusion. We discuss here the…
Direct reconstruction of the band structure of a 1D optical lattice with thermal atoms
Arnaud Courvoisier, Amruta Gadge, Nir Davidson
We report on a simple method to reconstruct the band structure of a 1D optical lattice using a thermal cloud with a momentum spread of about two-photon recoils. We image the moment…
High phase space density loading of a falling magnetic trap
Ido Almog, Jonathan Coslovsky, Gil Loewenthal +2
Loading an ultra-cold ensemble into a static magnetic trap involves unavoidable loss of phase space density when the gravitational energy dominates the kinetic energy of the ensemb…
Observing Power-Law Dynamics of Position-Velocity Correlation in Anomalous Diffusion
Gadi Afek, Jonathan Coslovsky, Arnaud Courvoisier +2
In this letter we present a measurement of the phase-space density distribution (PSDD) of ultra-cold \Rb atoms performing 1D anomalous diffusion. The PSDD is imaged using a direct…
