CARNET NOIR

Disparition de Jocelyne Guéna

C'est avec une immense tristesse que nous vous faisons part du décès de notre chère collègue Jocelyne Guéna qui nous a quittés brutalement le 16 août à l'âge de 61 ans.
Jocelyne Guéna était directrice de recherche au CNRS. Ancienne élève à l'Ecole Normale Supérieure, elle a obtenu son Doctorat d'Etat en 1985 au Laboratoire Kastler Brossel, sur la première observation de la Violation de la Parité dans l'atome de césium, qui constitue un test expérimental à basse énergie des théories d'unification des interactions fondamentales. En tant que chercheuse au CNRS, Jocelyne Guéna a poussé la précision de ces mesures de Violation de la Parité et reçu en 1999 le prix Servant de l'Académie des Sciences pour sa contribution à ce champ de recherche.
En 2005, Jocelyne Guéna a effectué un changement de thématique vers la métrologie des étalons de fréquence. Elle a passé deux années en Suisse, à l'Observatoire de Neuchâtel puis au METAS à Bern, où elle a participé au développement d'une fontaine atomique à jet de césium continu refroidi par laser. En 2007, elle a rejoint le SYRTE à l'Observatoire de Paris où elle s'est consacrée au développement à l'état de l'art des fontaines à atomes froids de césium et de rubidium, à leur exploitation pour l'amélioration des performances en métrologie temps-fréquence et pour réaliser des tests de physique fondamentale. Son implication exceptionnelle a permis de transformer ces extraordinaires objets de recherche que sont les fontaines atomiques en des outils pour la recherche fondamentale et pour les services scientifiques, tels que le Temps Atomique International et le Temps Universel Coordonné. En 2017, ses travaux ont été récompensés par le prix de la Recherche du Laboratoire National de métrologie et d'Essais.
Tous ceux qui ont bien connu Jocelyne garderont le souvenir d'une chercheuse passionnée, et dont la rigueur scientifique n'avait d'égal que la modestie. Ses qualités humaines, ses compétences scientifiques et son sens profond de l'intérêt général l'avaient conduite à prendre des responsabilités importantes au sein du SYRTE et de la communauté temps-fréquence.

PUBLICATIONS

EPJ QT special issue: "Quantum Metrology & Quantum Enhanced Measurement"

Quantum technologies are one of the major future challenges for research and science, but also a major opportunity for industry with respect to innovation and high technology. Indeed, quantum technologies and devices have already started to have an impact in industry, and several large companies are now developing new quantum devices or have started to integrate already existing devices into their products.
The exploitation of quantum effects in customised systems can lead to devices with superior performance and capabilities for sensing, measuring and imaging. The aim of this Special Issue on Quantum Metrology & Quantum Enhanced Measurement of the European Physical Journal Quantum Technology is to present cutting-edge research in the context of all these R&D quantum technology domains, as well as to highlight activities aiming to develop the necessary standardisation and metrological infrastructure for the characterisation and certification of the new quantum-based devices.
We invite you to submit articles for this special issue.
The special issue will be published as a Topical Collection in the framework of the Continuous Article Publication scheme allowing the usual EPJ Quantum Technology fast publication schedule whilst maintaining rigorous peer review; all articles must be submitted online, and peer review is managed fully electronically by the editors of the Special Issue.
Submissions are accepted from now until 30 June 2021.

RBL_2762

ACES Workshop

October 28-29, 2019, Institut d'Astrophysique de Paris (Paris, France).
This joint meeting of the ESA Topical Teams "ACES & General Relativity" and "ACES & Geodesy, clocks and time" focuses on the utilization of ACES and highly accurate clocks in space, both from a point of view of space geodesy and fundamental physics. Topics of interest are:
  1. The application and potential of highly accurate Clocks in Space such as ACES
  2. Tests of the Einstein Equivalence Principle (EEP)
  3. Laser Time Transfer using Satellites such as ACES and T2L2
  4. Future applications of coherent time in space geodesy
  5. The distribution of accurate time and frequency for metrology and geodesy
The colloquium will bring together the scientific community interested in the applications of highly accurate space clocks like ACES/PHARAO in all domains, from theoretical physics to cold atoms and application in geodesy and atmospheric studies. Furthermore we look at the scientific potential of near lossless links among high performing ground clocks and satellite clocks, both in time and frequency.
The meeting will consist of invited and contributed presentations on the details of ACES, data analysis and scientific applications. Whilst centered on ACES/PHARAO the colloquium is open to more general contributions on theory and experiments in any of the related subject areas. The aim is to prepare within the broad scientific community for the upcoming launch (2020), the scientific exploitation of the data and the development of new applications in space geodesy.
The workshop will include both review and contributed talks with ample time for discussion.
Deadline for abstract submission: September 15, 2019.

OFFRES D’EMPLOI

Post-doctoral position on the subject "Ultra-cold atoms in an all optical bubble shaped trap"

LP2N laboratory (Bordeaux, France).
The research topics is related to quantum gazes in microgravity and precision measurements. The first part of the project addresses bubble-shaped quantum gas (3-D spherical shell confinement), both on the theoretical aspect of the trapping and imaging and the experimental aspect. The project relies on the new quantum gaz in microgravity experiment, which will also address tests of gravity radiometry measurement with ultra-cold atoms in microgravity.
The ideal candidate should have a PhD degree in physics, a background in
experimental atomic physics, quantum gazes or atom interferometry. The first part of the work will consist in modelling the new experiment to produce a bubble-shaped trap for ultracold atoms. The study will include a complete characterization of the method including the loading in the trap, the atom losses, the heating rate, and the nature of the cold atom gas itself in function of the temperature and the atom-atom interactions. Additionally, the microscopic and macroscopic theory of the ultra cold atom gas in the bubble-shaped trap will be studied in interaction with theory groups in condensed matter physics or fluid mechanics in Bordeaux. The second part of the work will consist in implementing the experiment.

Junior Research Group Leader for the research group focusing on Novel Frequency References

Physikalisch-Technische Bundesanstalt (Braunschweig, Germany).
At PTB, we currently achieve lasers with the best frequency stabilities worldwide. We employ these ultra-stable frequency references with high phase coherence in our optical clocks and in tests of fundamental physics. In anticipation of the expanding applications of ultra-stable frequency references, particularly for fundamental metrology and for portable devices, we seek an outstanding candidate to head an experimental research group at PTB, which will meet the diverse, long-term needs of this field.
Under the mentoring of a PTB scientist, we expect close collaboration with fellow PTB scientists and partners within the QuantumFrontiers Cluster of Excellence on current research pursuits; these include research activities on ultra-stable optical cavities, low-thermal-noise mirrors and improved optical clock performance.
PTB, TU Braunschweig and Leibniz University Hannover offer an exciting collaborative research environment at an internationally competitive level as well as laboratories with state-of-the-art facilities.
To establish your own personal research activities in this field, the position includes core support from the Cluster of Excellence for funding a PhD student as well as for equipment for your own research activities in this field such as optical cavities at ultralow temperatures, active atomic light sources, solid-state-based narrow linewidth frequency references and micro-optical systems.
The position is initially limited to three years. After successful evaluations, the position can be extended for three more years and afterwards changed into a permanent staff position at PTB.
