Abelian sandpiles on Sierpinski gasket graphs
Robin Kaiser, Ecaterina Sava-Huss, Yuwen Wang
The aim of the current work is to investigate structural properties of the sandpile group of a special class of self-similar graphs. More precisely, we consider Abelian sandpiles o…
Towards a measurement of the Debye length in very large Magneto-Optical traps
Julien Barré, Robin Kaiser, Guillaume Labeyrie +2
We propose different experimental methods to measure the analog of the Debye length in a very large Magneto-Optical Trap, which should characterize the spatial correlations in the…
Self-sustained oscillations in a Large Magneto-Optical Trap
Guillaume Labeyrie, Franck Michaud, Robin Kaiser
We have observed self-sustained radial oscillations in a large magneto-optical trap (MOT), containing up to Rb atoms. This instability is due to the competition be…
Robust coherent transport of light in multi-level hot atomic vapors
Nicolas Cherroret, Michal Hemmerling, Victor Nador +2
Using a model system, we demonstrate both experimentally and theoretically that coherent scattering of light can be robust in hot atomic vapors despite a significant Doppler effect…
Towards a random laser with cold atoms
William Guerin, Nicolas Mercadier, Franck Michaud +7
Atoms can scatter light and they can also amplify it by stimulated emission. From this simple starting point, we examine the possibility of realizing a random laser in a cloud of l…
Controlled Dicke Subradiance from a Large Cloud of Two-Level Systems
Tom Bienaime, Nicola Piovella, Robin Kaiser
Dicke superradiance has been observed in many systems and is based on constructive interferences between many scattered waves. The counterpart of this enhanced dynamics, subradianc…
