I graduated in Physics at École Normal Supérieure de Lyon (2002), obtained Masters in Didactics and History of Science (Université Lyon 1, 2004) and Theoretical Physics (Université Aix-Marseille, 2005), and a PhD in Physics (Universite Aix-Marseille, 2008). In São Carlos SP (Brazil) since 2011, I am working on light-matter interaction, with an emphasis on light scattering by atomic clouds, as well as long-range interacting systems. Since Feb. 2017 I am a junior Professor at the Department of Physics of the Federal University of São Carlos (Source: Lattes Curriculum)

This proposal aims at two parallel sets of activities in research and higher education that will be carried out by team of experimentalists and theorists from Sweden and Brazil. The main research topic is tightly bound to quantum technologies and addresses the use of quantum dots for quantum communication and simulation. In particular, we will employ light-mediated interaction between qua…
Large ensembles of cold atoms present strong cooperative properties as they scatter light, which results in a modified spontaneous emission. While cooperative scattering has been extensively studied up to date, its consequences on stochastic effects and on optical forces are still to be investigated, and it is the two objectives of the present project. The first goal will be to elucidate …
Devices for quantum information computation and communication require the combined use of different quantum systems: photons can transmit informations over large distances, cold trapped atoms can bemanipulated to enable quantum information processing, and atomic ensembles are suited for long-livedquantum memories, as well as non-linear generation of non-classical correlations. Cold atoms …

The present project aims at investigating the presence of 'cooperative robustness' and 'shielding' for systems with long-range interactions: these effects are the signatures of the emergence of two dynamics with very different time scales (one very fast compared to the single-particle dynamics, and the other very slow), which subspaces are essentially decoupled. The project addresses both…

This project addresses the nonlinear interactions between photons in clouds of cold neutral atoms. While dipole-dipole interactions are known to lead to non-classical atomic states and potentially entanglement, the possibility to generate non-classical light is essentially unexplored. As a first step, we propose to investigate the anti-blockade mechanism, in analogy with Rydberg atoms, to…
This project addresses the nature of subradiance (long-lived scattering modes) in cold atomic clouds, focusing on the statistics of the emitted light. The objective is to elaborate a test that permits to distinguish subradiance (the counterpart of superradiance, which corresponds to an accelerated emission) from radiation trapping (an incoherent phenomenon) or from (Anderson) localization…
This project at showing how ultracold atomic clouds may turn coherent light into a chaotic one, even in absence of motion and of interactions: The resonance fluorescence, which reflects the broadening of the emission when the atoms are saturated, leads to a 'randomization' of the phase of the emitted wave. As a witness of the chaotization of the emitted wave, the Siegert relation, which r…

The post-doctoral researcher will investigate this memory effect in 2D with vectorial light, as well as in 3D in the different regimes (scalar and vectorial light, including using a strong magnetic field or diagonal disorder to modify the scattering kernel). One particular objective will be to design a scheme to detect this effect in a 3D cold atom cloud. (AU)
This project aims at determining whether many-body localization is possible for moderately driven atoms coupled in 2D and 3D through dipole-dipole interactions, and which are its signatures (level spacing, radiation dynamics).
This project corresponds to the final phase of the Direct PhD of the candidate, which started in July 2015, and will end in July 2018 due to the conclusion of the Young Researcher Project of the supervisor. The candidate will conclude three projects which are well advanced. The first addresses subradiance and superradiance in clouds of saturated atoms. The second, initiated during a BEPE …

We aim at exploring the properties of trapped Rydberg ions to study its potential for quantum information processing tasks. More specifically in this project we will focus on realistic schemes for quantum operations and their experimental realizations in a system of Strontium ($^{88}$Sr$^{+}$) ions. To this end, one needs to take into account the properties of $^{88}$Sr$^{+}$ ions when ex…
This project aims at investigating the intensity of the emitted far-field by dilute atomic clouds where the light-mediated long-range interaction predominates. Spontaneous emission and interference effects then play an important role, differently from subwavelength systems of Rydberg atoms, yet the multiple scattering of light allows for remote atoms to exhibit correlations. During this i…
In this research internship abroad project we address the possibility of generating entanglement and other phenomena resulting from quantum correlations in cold atomic ensembles scattering light, focusing on the dilute limit, where dipole-dipole interactions are dominated by the far-field terms. Atomic clocks in optical lattices are particularly interesting platforms to implement this lim…
This project addresses correlations in the light scattered by disordered atomic clouds, due to the interaction between atomic dipoles. We will study both classical and quantum effects, with a special attention to experimental signatures, in order to interpret and stimulate experiments in the INPHYNI. In particular, we aim to investigate the light statistics of speckle (for ex., the Sieger…
