Spatial instabilities in a cloud of cold atoms
Rudy Romain, Antoine Jallageas, Philippe Verkerk +1
Dense cold atomic clouds have been shown to be similar to plasmas. Previous studies showed that such clouds exhibit instabilities induced by long-range interactions. However they d…
Measuring the re-absorption cross section of a Magneto-Optical Trap
Rudy Romain, Hélène Louis, Philippe Verkerk +1
Magneto-Optical Traps have been used for several decades. Among fundamental mechanisms occuring in such traps, the magnitude of the multiple scattering is still unclear. Indeed, ma…
Phase-space description of the magneto-optical trap
Rudy Romain, Daniel Hennequin, Philippe Verkerk
An exhaustive kinetic model for the atoms in a 1D Magneto-Optical Trap is derived, without any approximations. It is shown that the atomic density is described by a Vlasov-Fokker-P…
Synchronization in non dissipative optical lattices
Daniel Hennequin, Philippe Verkerk
The dynamics of cold atoms in conservative optical lattices obviously depends on the geometry of the lattice. But very similar lattices may lead to deeply different dynamics. For e…
How to characterize the dynamics of cold atoms in non dissipative optical lattices?
Daniel Hennequin, Philippe Verkerk
We examine here the classical dynamics of cold atoms in square optical lattices, i.e. lattices obtained with two orthogonal stationary plane waves. Contrary to much of the past stu…
Dark Optical Lattice of Ring Traps for Cold Atoms
Emmanuel Courtade, Olivier Houde, Jean-François Clément +2
We propose a new geometry of optical lattice for cold atoms, namely a lattice made of a 1D stack of dark ring traps. It is obtained through the interference pattern of a standard G…
