Welcome to the “Quantum Optics – Atoms” group, led by Antoine Browaeys. We are part of the Laboratoire Charles Fabry (UMR 8501 of CNRS) of Institut d’Optique.

Our research focuses on experimental studies of the effects of strong dipole-dipole interactions in strongly correlated systems of a few atoms.

News

November 2018: We have internship positions available on all our projects. Some could lead to PhDs starting in 2019 (Light scattering project, Rydberg project, cell project). Please contact any of the group permanent staff member: Antoine Browaeys, Thierry Lahaye, Igor Ferrier-Barbut and Yvan Sortais.

5 november 2018: Kai-Niklas Schymik from Heidelberg has joined our group as a PhD student to work on our project on Rydberg atoms in a cryostat. Welcome to France Kai!

1 November 2018: Check out the new preprint from the Rydberg lab: arXiv:1810.13286. We use Rydberg atoms to implement a version of the SSH model for hard-core bosons, thus realizing a symmetry-protected topological phase.

1 October 2018: Igor Ferrier-Barbut joins the group as a CNRS researcher. Welcome, Igor!

6 September 2018: Our 3D paper is now published in Nature 561, 79 (2018).

18 June 2018: Our paperObserving the Space- and Time-Dependent Growth of Correlations in Dynamically Tuned Synthetic Ising Models with Antiferromagnetic Interactions”, in collaboration with our theory colleagues from Innsbruck, is now published in Phys. Rev. X ! Kaden Hazzard writes nice a Physics Viewpoint about these results.

January-March 2018: We start working on a new setup. Here are the highlights of the first weeks…

16 March 2018: Our paper “Accurate Mapping of Multilevel Rydberg Atoms on Interacting Spin-1/2 Particles for the Quantum Simulation of Ising Models“, written in collaboration with our theory colleagues S. Weber and H.-P. Büchler from Stuttgart, is now published in Phys. Rev. Lett!

3 January 2018: Tom Peyrot, who did the first part of his PhD in Durham (UK) at the JQC with Charles Adams, is back to the Institut d’Optique for the end of his PhD. Eric Magnan, who did the first part of his PhD at the University of Maryland (USA) at the JQI with Trey Porto, is also back in Palaiseau. Tom, Eric, welcome!

7 December 2017: Our new paper about full-loaded 3D arrays of single atoms is out on the preprint server (arxiv:1712.02727). Here is an example of structure we can build:

October 2017: Our colleague and friend Matthias Weidemüller from Heidelberg writes about our research in a nice article in the October 2017 issue of Physik Journal (the magazine of the DPG, the German Physics Society).

2 August 2017: Our addressing paper is appears in Phys. Rev. Lett. and is selected as an Editor’s suggestion!

July 2017: Vincent won one of the Best Poster Awards at the International Conference on Laser Spectroscopy 2017, held in Arcachon, and also at YAO 2017, held in Paris. Congratulations, Vincent!

10 May 2017: We post on the preprint server our latest paper : arXiv:1705.03293. We use an addressing beam at 1005 nm to selectively ligthshift a Rydebrg state and thus control at will the resonant dipole-dipole interaction between two atoms.

1 Februrary 2017: Henning Labuhn receives one of the EDOM thesis prizes. Congratulations, Henning!

3 December 2016: Our atom-assembler paper is published in Science!

11 July 2016: We post on the arXiv our manuscript “An atom-by-atom assembler of defect-free arbitrary 2d atomic arrays”. The image below should be enough to describe the main point of the paper:

21 April 2016: Our paper “Tunable two-dimensional arrays of single Rydberg atoms
for realizing quantum Ising models” has just been accepted for publication in Nature!
