Les Houches pre-doctoral school on “Quantum simulations with ultracold atomic gases”, September 13-24, 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.

NASA Workshop Announcement: 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.

Workshop “Optical Clock Comparison using VLBI” – will be held virtually

The workshop aims at discussing  advanced clock comparison using VLBI with the support of advanced GNSS techniques and fiber links, and is organised by the Italian and Korean NMIs (INRIM and KRISS), the Italian Institute of Astrophysics (INAF), the Korea Astronomy and Space Science Institute (KASI), the Korea Institute of Science and Technology Information (KISTI) and the Korea Advanced Institute of Science and Technology (KAIST).

It includes both invited sessions upon general aspects & advances in the field of optical clocks, VLBI technologies and international clock comparisons, followed by more technical sessions specifically dedicated to the design of a VLBI clock comparison campaign between Italy and Korea.
A program can be found at https://sites.google.com/view/occ-vlbi, where more info will be posted soon.

We kindly ask you to fill the registration form below by May 27th, 2021. The meeting links will be sent out to registered participants before the workshop.

Several Post-doc, PhD, master student positions available at Max-Planck Institute of Quantum Optics (Garching, Germany).

We are starting exciting new experimental projects (in the fields: optical frequency combs, frequency metrology, nonlinear optics, photonics) and we have openings at all levels (post-doc, doctoral/PhD student, master student) for young scientists to join our group.
We can also welcome senior scholars on sabbatical leave (>3 months).
Our group is part of the Max-Planck Institute of Quantum Optics, (Garching, Germany).

The topics of the projects are:

–       Precision spectroscopy of small molecules for tests of fundamental physics

–       Digital holography and 3D-imaging

–       Quantum-enhanced interferometry with frequency combs

–       Frequency combs and frequency-comb spectrometers on a photonic chip


All projects require a passion for challenging experiments and a strong background in optics. Knowledge in atomic/molecular/quantum physics is an asset.

The positions are available immediately and will remain open until filled.

More information may be found in the attachments and at our website http://frequency-comb.eu

Applications and enquiries should be addressed to nathalie.picque@mpq.mpg.de.
