Wave propagation in diffusive media is an important subject for numerous fields (medical imaging, acoustics, seismology, stellar physics, …). The experiments that we pursue make use of an original medium: a laser-cooled atomic cloud. The peculiar properties of this diffusive medium (strong resonances, strong nonlinearity, quantum internal structure of the scatterers, mechanical effects of light on the atoms, quantum effects…) give rise to a very rich physics. We study several subjects in this context.
More generally, we are interested in collective effects in light-atom interaction, which include multiple scattering of light but also nonlinear optics or cooperative scattering.
We have also studied dynamics of matter waves with a Bose-Einstein condensation experiment.
Finally, we have been involved in a fruitful collaboration with astrophysicists on the measurement of light correlations (Hanbury Brown and Twiss technique).
Our work is mainly experimental, using three cold-atom apparatus and several smaller hot-vapor setups, but also theoretical, in particular through many collaborations.

News & Events

Oct. 2020: Open post-doc position

We have an opening for a two-years post-doc position on intensity correlations to probe quantum correlations in a cold atomic cloud, see the annoncement.

Oct. 2020: Welcome to the new members of the team!

Martial Morisse and Stephan Asselie have started their PhD in our team. They will work respectively on the "Rb1" and "Rb2" experiments.

Sept. 2020: Collaborative ANR grant awarded - PI: William Guerin

The I2C project (Intensity Interferometry at Calern) is a collaborative project involving three teams from the Nice area: our team at INPHYNI (William Guerin, Mathilde Hugbart, Guillaume Labeyrie and Robin Kaiser), astrophysicists/astronomers from the Lagrange Laboratory (Olivier Lai, Jean-Pierre Rivet, Armando Dominiciano de Souza, and Farrokh Vakili), and time-metrology experts of the Géoazur Laboratory (Julien Chabé, Clément Courde, and Nicolas Maurice). Our partners operate the C2PU and MéO telescopes from Observatoire de la Côte d'Azur (on the Calern Plateau). The goal is to revive the technique of intensity interferometry with modern technologies and use it for measurements of astrophysical interest.

August 2020: Publication in Physical Review Letters

The paper "Photon Blockade with Ground-State Neutral Atoms" has been published in PRL! This paper proposes a scheme to achieve photon blockade in very dense atomic ensembles.

Robin has been awarded the "Grand Prix 2020 en sciences physiques de l'Institut Grand-Ducal / Prix Paul Wurth", see the press release here. Congratulations to him! A ceremony should take place in November (if not canceled by the Covid-19 crisis).

May 2020: Book by Anders Kastberg

Anders has published a book on the Structure of multielectron atoms (Springer).

Research

Our main current research topics are:

Cooperative scattering

When a photon is sent onto an atomic ensemble, it interacts collectively with the N atoms of the cloud and not simply with one of them. This results in measurable modifications in the scattering rate, the emission diagram or the temporal dynamics. We study these cooperative effects experimentally and theoretically. Recently, remarkable results have been obtained, in particular the direct observation of subradiance and superradiance in the linear-optics regime. This research topic is currently funded by the ANR project QuaCor, the QUANTERA project PACE-IN, and the EU project ColOpt.

Fluctuations and correlations of light: from atoms to stars

We study the fluctuations and correlations of light after interaction with cold or hot atomic vapors, either after transmission through the atoms, or after scattering by the atoms, in the single and multiple scattering regimes. We also collaborate with astrophysicists of the Observatoire de la Côte d'Azur to work towards the revival of intensity interferometry (Hanbury Brown and Twiss technique) with modern photonic technologies. This research topic is currently funded by the ANR project QuaCor and the Région PACA project I2C.

Nonlinear optics: superfluid light and self-organization

Atomic vapors have strong optical nonlinearities that we use in experiments with hot or cold vapors. In the latter case, the mechanical aspect plays also a role, with the spontaneous formation of atomic-density patterns. This research topic is currently funded by the EU projects ColOpt and PhoQus.

Localization of light

When a wave propagates in a strongly disordered medium, it is predicted that above a certain level of disorder, interference effects completely block the wave diffusion. This so-called Anerderson localization has never been clealy observed for light. We have been studing, at a theoretical level, if and how a cold-atom cloud could be an appropriate medium for observing this effect. We are now building a new cold-atom experiment in order to experimentaly observe this effect.This research topic is currently funded by the ERC project ANDLICA.

Light-induced long-range forces

We also study the mechanical action of light on cold atoms during the multiple-scattering process. For example, it can give rise to mechanical instabilities, which we studied experimentally and theoretically. Moreover, it gives a force that is long-range, like Coulombian and gravitational interactions. As a consequence, there are interesting analogies with plasma physics and gravitational systems. This research topic is currently funded by the EU project ColOpt.
