Détachement d’une année : Développeur en comparaisons temps/fréquence par GNSS, au BIPM

The BIPM (International Bureau of Weights and Measures) invites applications for a one-year secondee position in the Time Department, for developments in the field of GNSS time/frequency transfer with PPP and IPPP. The position may be extended to a second year.

Applications should be sent by 20 June 2021.

See more information on duties, employment conditions of such a secondee position, expected qualifications and experience, as well as on the application process in the announcement “One-year secondment – Developer in GNSS time/frequency transfer” at https://www.bipm.org/en/opportunities .

The BIPM is located at the Pavillon de Breteuil, Sevres, France, situated in the outskirts of Paris. The Time Department computes and disseminates the international reference time scale Coordinated Universal Time (UTC), and provides traceability to the international system of units (SI) to local realizations of UTC maintained in national institutes.

EFTS 2021 – European Frequency and Time Seminar

The EFTS is a no-profit intensive full-week seminar intended to provide education and training with lectures and lab sessions. It targets the broadest audience: Engineers, Ph.D. students, post-docs, young scientists, newcomers, etc.

This seminar is unique in the following:

  • Broad spectrum of topics related to time and frequency
  • Balance between academic and applied issues
  • Broad target audience, yet keeping high level education
  • Lab sessions. The participants work themselves in small groups with a wide range of instruments made available.

The high level of training is guaranteed by the world-class Scientific Council and lecturers from the major European and International Institutions

École pré-doctorale aux Houches sur “Quantum simulations with ultracold atomic gases”, du 13 au 24 septembre 2021

We are organizing a pre-doctoral school in Les Houches from 13 to 24 September 2021. This school is mainly intended for students at the early stage of their PhD. Depending on availability, a few applications from PhD students at a later stage in their graduate career could also be accepted, as well as junior post-doctorant researchers. It consists in a two weeks master course on the physics of cold atoms including the recent advances in this field. The first week will cover general aspects. The second week will focus more specifically on quantum simulations with cold atoms.

For more information, please visit the website: https://coldatoms2021.sciencesconf.org/ .

Lectures will be given (in English) by

Franck Pereira Dos Santos (LNE-SYRTE, Observatoire de Paris, France): Laser cooling and trapping

Ana Maria Rey (NIST-JILA, University of Colorado, USA): Ultra-cold collisions

Mikhail Baranov (University of Innsbruck, Austria): Quantum gases and superfluidity

David Clément (Laboratoire Charles Fabry, Institut d’Optique, France): Optical lattices

Monika Aidelsburger (University of Munich, Germany): Periodically driven optical lattices and topology

Hans-Peter Büchler (University of Stuttgart, Germany): Quantum magnetism

Thierry Giamarchi (University of Geneva, Switzerland): Quantum transport

Zoran Hadzibabic (University of Cambridge, UK): Non-equilibrium dynamics

Iacopo Carusotto (University of Trento, Italy): Quantum simulations with quantum fluids of light

The deadline for applications is June 13, 2021. The selection of the applicants will be done at the beginning of July. 

The school is planned to be held in-person, but as the situation is always evolving due to the Covid-19, we will keep you updated.

Workshop de la NASA sur “High Performance Clocks in Space for Fundamental Physics/Science”

The Biological and Physical Sciences (BPS) Division of NASA’s Science Mission Directorate (SMD) will hold a workshop on June 17, 2021, at 8-11 am Pacific Time (15-18 UTC) with two principal goals: (i) seeking community input on possible future missions focused on precision measurements/tests of fundamental physics using high performance clocks in space and (ii) organizing the preparation of white papers in response to the upcoming Call from the Decadal Survey Committee. Central to the discussion will be a recent mission concept (Fundamental physics with an Optical Clock Orbiting in Space) that proposes to place an optical clock in an elliptical orbit to test General Relativity, but all types of clocks-in-space-based fundamental physics research are encouraged (gravitational wave detection, dark matter searches, drifts of fundamental constants, etc.). Also encouraged will be the development of essential supporting technologies including time transfer, optical clocks, and space-qualifiable lasers.

The Workshop will begin with several brief presentations on science possibilities for optical clocks in space with generous time allotted for follow-up questions and discussions. We will conclude this first session with a presentation on the FOCOS mission concept followed by discussion. Following a short overview on the white paper process, we will then have break-out sessions focused on organizing authors and topics for potential white paper submissions. NASA/JPL scientists will be on hand to answer questions.

Attendees are encouraged to register one week in advance and submit one PowerPoint slide describing their white paper focus interests, which they will be able to present during the break-out sessions. The slides will be used to help organize the break-out sessions around the topics of greatest interest to the attendees and to jump start the white paper process.

Expected Workshop output: We hope the workshop will help to generate many interesting and high quality white paper submissions in the space clock science area as well as to identify potential lead authors for various topic areas.

Workshop materials (templates, reference documents to be added as available): High-Performance Clocks in Space – Google Drive. The meeting link for the June 17th workshop will be provided in a future announcement closer to the Workshop date.

Please feel free to contact me with any questions. We look forward to seeing you at the Workshop.
