Inscription and submission to PhDay Conference @Saclay are opened

Together with Géraud Dupuis and David Theidel, we organize a conference that aims to connect Saclay students (Master, PhD, PostDoc) of quantum related subjects and provide them a nice opportunity to present the research project they are involved in. Inscription and contributions are opened.

Our paper on sub-shot noise interferometry was published in Phys. Rev. A !

image We have just published :heart_eyes: :cocktail: a new article focusing on sub-shot-noise interferometry with two-mode quantum states. In this paper, we compare the advantage of different input state - twin-fock or two-modes squeezed state - when taking into account the losses due to the finite efficiency of the detector. We also provided our analytical formulas in a python package qsipy, making possible for experimentalists to check the sensitivity of their interferometer depending on the input state and detector properties. The PDF version with the supplemental material can be downloaded here .

Talk @LKB in Paris

A meeting was organized by the analog gravity community to discuss the topic of analog cosmology. The goal of this meeting was to gauge the level of interest in a “Transverse Task Force” of the GDR COPHY. My slides are available here.

Some changes in the team !

The Quantum Atom Optics team has undergone some changes: Clothilde just arrived to start her PhD, while Quentin left us to work at ONERA. Paul joined our team for a 6-month internship before returning to LCF to work on the other helium experiment . Of course, Charlie, Denis, and Chris are still here!

Analog Gravity Summer School

I just come from the Benasque Analog Gravity Summer School & workshop :star: :books:. The first week of the stay was the summer school, aiming to train the new generation of researchers. The second week brought together an expanding community of experimental and theoretical physicists who shared their work, with very nice presentation and discussions. Quentin presented our latest advanced and I presented a poster. A heartfelt :cupid: thank you to the organizers for facilitating such enriching experiences!

Laboratory Charles Fabry scientific days

This Monday, March 27th, the scientific day of the Charles Fabry laboratory took place, which I co-organized. I also presented the actions of the 'Ecology' working group of the laboratory, including the Carbon Footprint calculation method implemented by Lab 1.5.

Theoretical result by Amaury & Scott

image Amaury and Scott just published a paper in the last 2022 issue of Physical Review B, where they study Phonon decay in one-dimensional atomic Bose quasicondensates via Beliaev-Landau damping. Especially, using the Fermi golden rule, they derive a simple analytic formula for the decay rate of the phonon occupation number. Their result can explain why the 2012 experiment did not witnessed entanglement. Do not hesitate to have a look!

New doctor in the team

Quentin successfully earned his PhD today – congratulations :smile: ! Do not hesitate to have a look to his manuscript. His thesis defense gathered the last five PhD students who contributed to the experiment, encompassing the doctoral candidates from 2016 to 2024.

Fête de la science

This weekend, the Institut d'Optique welcomed visitors as part of the Fête de la Science. We were able to introduce the general public to our experiments on cold atoms, popularize our research work, and explain the basic principles of laser cooling. The poster we presented can be downloaded as a pdf or svg.

PhD scholarship award

I just got a grant to realize my PhD :microscope: under the supervision of Chris Westbrook and Denis Boiron in the Quantum Atom Optics team, at Institut d’Optique Graduate School. My grant comes from the Quantum Paris-Saclay program and the Ile-de-France region under the SIRTEQ program .
