EPS Edison-Volta 2018 Prize for Alain Brillet

The European Physical Society (EPS), the Fondazione Alessandro Volta and Edison S.p.A. have awarded the 2018 European Physical Society Edison Volta Prize to:

  • Alain Brillet (Observatoire de la Cote d’Azur, CNRS, Université de la Côte d’Azur, Nice, France)
  • Karsten Danzmann (Max-Planck-Institut für Gravitationsphysik and Leibniz University, Hannover, Germany)
  • Adalberto Giazotto † (INFN, Pisa, Italy) and
  • Jim Hough (University of Glasgow, UK)

“for the development, in their respective countries, of key technologies and innovative experimental solutions, that enabled the advanced interferometric gravitational wave detectors LIGO and Virgo to detect the first gravitational wave signals from mergers of Black Holes and of Neutron Stars.”

The EPS Edison Volta Prize promotes excellence in research and is given in recognition of outstanding research and achievements in physics. The Prize is given biennially to individuals or groups of up to three people. The laureates receive a medal, which is a faithful reproduction of the Medaglia Premio dell’ Associazione per l’Incremento del Commercio in Como: a portrait of Alessandro Volta together with the saying: Alexandro Voltae Novocomensi, i.e. (dedicated) to Alessandro Volta from Novum Comum, which was the old name given to the city of Como by Julius Caesar.

The Prize was established in 2011 and was awarded for the first time in 2012 to R. D. Heuer, S. Bertolucci and S. Myers from CERN, Geneva and in 2014 to J.-M. Raimond from the Laboratory Kastler Brossel at the Collège de France, Paris. It was also given to three principal scientific leaders of the ESA’s Max Planck Mission in 2015 in the frame of the International Year of Light 2015: N. Mandolesi, University of Ferrara, J.-L. Puget, Institut d’Astrophysique Spatiale, Université Paris Sud & CNRS, and J. Tauber, Directorate of Science and Robotic ESA (NL).

  • oster interaction between GNU Radio usersShare knowledge about GNU Radio developpement through tutorials, seminars and demos
  • Bridge the gap between technical/engineering and scientific/research points of view on topics related to applied research with GNU Radio.

Such topics include:

  • Software
  • Defined Radio, radio prototyping,RF design,
  • RADAR design
  • Signal processing in embedded systems,
  • GNU Radio development environment,
  • New platforms

27th of March 2018 (Paris) – PhD defense of François Tricot

François Tricot will defend his thesis on 27th of March 2018 at 1:30 pm on the subject “Analysis and reduction of the frequency instability noise sources in a compact CPT clock”, realized in SYRTE under the direction of Stéphane Guérandel.

The defense will take place in the amphitheater of the Institut d’Astrophysique de Paris (IAP), in front of the jury: Agnès Maître, Frédéric Du Burck, Vincent Giordano, Virgile Hermann and Jean-Marc Lesage.

Abstract: This thesis work has been granted by a CIFRE-Défense contract to study the frequency stabilities of an atomic clock based on coherent population trapping. The objective is to demonstrate a frequency stability in the range of 10-13τ-1/2 up to 10 000 s. A caesium vapour cell is used with a high-contrast excitation scheme using cross linear polarisations and a Ramsey interrogation. The short-term frequency stability is presented with the reduction of the phase and the laser power noise, both limiting clock performance at 1 s integration time. The optimisation of the microwave chain with a new local oscillator, and the implementation of a very low noise power lock loop have improved the frequency stability down to 2,3×10-13 at 1 s integration time. The fluctuations analysis of the operating parameters (laser intensity, magnetic field, temperature, etc.) and the measurement of the clock frequency show that the medium-term frequency instability is mostly limited by laser power and magnetic field fluctuations at the level of 2×10-14 at 2 000 s integration time. These analyses also show that laser power fluctuations, despite servo loop control, are related to polarisation fluctuations through temperature fluctuations inside the experiment isolation box. Finally, the studies of a dual-frequency and dual-polarisation laser for a compact CPT clock are presented, paving the way to industrialisation by reducing the optical bench.

Key words: atomic clock, vapour cell, coherent population trapping, Ramsey fringes, Dick effect, intensity noise, frequency stability.

2nd level Specializing Master’s Programme in Photonics for Data Networks and Metrology

Data traffic will experience a dramatic growth over the next years driven by 5G access, high-definition video, virtual and augmented-reality contents, and the considerable growth in cloud services due to Big Data Exchange. Photonic data networks will be required to be more and more pervasive and elastic, to supporting the paradigm of Internet of Thing and to enabling Industry 4.0.
Besides data transport, photonic networks will also distribute time and frequency (T/F) standards for research and industry, enabling orders of magnitude performance improvements with respect to satellite systems, over continental geographical areas.
The list of institutions supporting the initiative testifies the need for a vertical multidisciplinary knowledge, from the transmission layer up to the IP layer, and training such new professional figures is indeed the mission of the 2nd level Specializing Master’s Programme.
The Programme is supported by the EU through the project H2020-INFRAINNOV-CLONETS and will offer theoretical and practical lecturing, hand-on experiences and a final internship in European industrial and/or research environments.
Deadline for appliance: May 7th 2018.

ANR – JST joint call for two CREST research areas: “Quantum technologies”

JST and the French National Research Agency (Agence Nationale de la Recherche; “ANR”) concluded a Framework Agreement in December 2017.

The purpose of this Agreement is to foster Japanese-French collaboration in scientific research and to fund joint research projects conducted by Japanese and French partners eligible for funding from each agenc on:
Quantum technology: Creation of an innovative quantum technology platform based on the advanced control of quantum states

The full description of the two areas is appended to the document on the national regulations for French applicants.

The proposals should be led by a Japanese PI and a French PI and will be evaluated via a peer-review procedure by JST and ANR. The call is open to public and private partners.

The average ANR funding will be around 500 k€ per project depending on the number of partners and the ambition of the project, for a 5-year duration.

The JST-CREST call will be launched at a later date for non-joint proposals but the Japanese-French consortia must have submitted their proposals to ANR website before April 16th, 10AM CET.
