Measuring correlations between individual quantum particles - from ions and superconducting bits to atoms and molecules - holds large promises to reach a better understanding of some many-body problems. The research in our team goes along these lines with the investigation of single-atom-resolved correlations in strongly interacting quantum gases of metastable Helium. The project uses the recently built lattice gas machine which allows for the three-dimensional detection of individual bosons when released in a time-of-flight experiment (Cayla et al., Phys Rev A 2018, Tenart et al. arXiv 2019). The detector we use is specific to metastable Helium and it relies on the high internal energy stored in each atoms. It allows us to measure the momentum correlations between individual quantum particles and characterize non-trivial quantum states, such we have recently reported on a Mott insulator (C. Carcy et al., Phys. Rev. X 2019).
The candidate will be invited to participate to the exploration of two topics. Building on a recent work on the Mott state where correlations are of quantum statistical origin (C. Carcy et al., Phys. Rev. X 2019), we now aim at finding correlations induced by the presence of interaction and genuinely quantum. For instance we will look for signatures of non-Gaussian many-body ground-states close to the Mott phase transition and in dissipative lattices. The second part of the project will be dedicated to the realization of a Fermi sea of metastable Helium-3 and the study of correlations in Bose-Fermi mixtures. This second line of research will require the building of the laser cooling setup for Helium-3. The post-doctoral position is funded through the project QUORUM from the Agence Nationale de la Recherche (ANR), which aims at the above-mentioned scientific objectives.
The candidate will have the opportunity to partially supervise the interns and/or PhD students working on the experimental apparatus.
PhD degree in experimental physics, a strong background in experimental atomic physics, quantum gases or condensed matter physics.
The candidate will work in the Lattice gas team, composed of two/three PhD students along with some interns, and supervised by D. Clément. The Lattice gas team is part of the Quantum gas group at the Institut d'Optique in Palaiseau, in the Paris area. The Quantum gas group holds 6 different quantum gas experiments and about 25 members.
