Research interests: Nonlinear waves and quantum fluctuations in superfluids of matter and/or light

I work as a CNRS postdoctoral researcher within the « Complex Quantum Systems » group of the Laboratoire Kastler-Brossel. With Nicolas Cherroret and Dominique Delande, I am interested in quantum fluctuations, prethermalization, and thermalization in disordered systems of interacting bosons. I also pursue my researches on propagating quantum fluids of light in collaboration with Alberto Bramati, Élisabeth Giacobino, and Quentin Glorieux from the experimental « Quantum Fluids of Light » team of the « Quantum Optics » group.

Prior to coming back to France, I was a SiQuro postdoctoral fellow at the BEC Center, working within the group headed by Iacopo Carusotto. There, my research mainly focused on the investigation of many-body phenomena in propagating quantum fluids of light. I collaborated—and continue collaborating—with Stefano Biasi, Lorenzo Pavesi, and Fernando Ramiro-Manzano from the Laboratorio di Nanoscienze and with Mathias Albert, Matthieu Bellec, and Claire Michel from the very new Institut de Physique de Nice. I also worked with Alessio Chiocchetta, who is now postdoctoral researcher at the Institut für Theoretische Physik, and was involved in discussions with the « Extreme Light » group headed by Daniele Faccio.

I completed my PhD at the Laboratoire de Physique Théorique et Modèles Statistiques under the supervision of Nicolas Pavloff and within the former École Doctorale de Physique de la Région Parisienne (ED 107), presently École Doctorale « Physique en Île-de-France » (ED 564). My thesis work mainly focused on the study of the acoustic Hawking radiation in atomic Bose-Einstein condensates. I was also interested in the superfluid and dissipative properties of fluids of light in semiconductor microcavities as well as in the formation of nonlinear waves in these systems and in two-component atomic Bose-Einstein condensates. I collaborated in particular with Anatoly M. Kamchatnov from the Institute of Spectroscopy. Here are my PhD manuscript (in French) and my PhD-defense slides (in English).
