On the entanglement of quasi-particles in a Bose-Einstein condensate
From Faraday waves to the Dynamical Casimir effect
Welcome!¶
This website contains the HTML version of my PhD thesis manuscript, for which the official PDF manuscript can be found here.
I worked under the supervision of Denis Boiron and Chris Westbrook, in the Quantum Atom Optics team at the Laboratoire Charles Fabry. The laboratory is part of the Institut d’Optique Graduate School, member of the Université Paris-Saclay.
My thesis project focused on probing the entanglement of quasi-particles in a parametrically driven Bose-Einstein Condensate. Furthermore, we connect this process to the Dynamical Casimir Effect and the reheating of particles in the early Universe, see the introduction! The outline of the manuscript, which contains six chapters, is shown below.

The team¶
Maintaining a Bose-Einstein condensate machine is a daily task carried out by a few people in parallel. The results reported here are therefore the outcome of a team effort, and I would like to warmly thank everyone who contributed to its success: the Quantum Atom Optics team (see Figure 2) as well as the COSQUA task force!

On the right picture, Paul Paquiez (before he left us for fermionic helium) and Clothilde Lamirault joined us. Bottom: Amaury Micheli, a theoretician collaborator visited us and Rui Dias also became part of the team.
Funding¶
My PhD project was funded by the Ile-de-France region, through the Sirteq DIM (1/2) and the Quantum Saclay network (1/2). During my PhD, the experiment has received funding from QuantERA Grant No. ANR-22-QUA2-000801 (MENTA) and ANR Grant No. 20-CE-47-0001-01 (COSQUA).
