Christophe Salomon wins the 2025 Balzan Prize
French physicist Christophe Salomon has been awarded the 2025 Balzan Prize by the Balzan Foundation for his pioneering work using ultra-cold atoms to build atomic clocks that have revolutionized time measurement.
Link to the press release from the Balzan International Foundation. The prize will be awarded in Bern (Switzerland) on November 14, 2025.
Research Engineer at LPL
Fixed-term position for a research engineer in the Metrology, Molecules, and Fundamental Tests research group at the LPL. The candidate will work on experimental developments for precision measurements and ultra-stable signal transmission, with a strong focus on electronics. Applications are open on the CNRS job portal: link.
HDR defense: Clement Lacroute
On Thursday, October 16, 2025, Clement Lacroute will defend his HDR entitled:
“Cavités Fabry-Perot ultra-stables et pièges à ions à électrodes surfaciques pour la métrologie des fréquences optiques”
The defense will take place at 2 p.m. in the Mesnages amphitheater at SUPMICROTECH-ENSMM (Besançon).

REFIMEVE 2025 Annual meeting- Grenoble – Registrations open
On behalf of the organizing committee, I am pleased to announce the opening of registration for the REFIMEVE 2025 General Assembly. You can do so here:
https://agrefimeve2025.sciencesconf.org/.
For logistical reasons, the registration deadline is November 7th at 12:00 PM UTC+1. Registration is free but mandatory, even for guests.
On the General Assembly website, you will find the full program, which includes laboratory visits on the morning of the second day. These will be organized into three parallel groups, including a visit to LIPhy. You are invited to prioritize the second laboratory on campus from among three options: IRAM, IPAG, and ISTERRE.
Workshop – Fundamental Physics in Space with Quantum Sensors
We are organizing an Aspen Center for Physics (ACP) winter workshop on Fundamental Physics in Space with Quantum Sensors, to be held February 22-27, 2026 in Aspen, Colorado, USA. The goal of this workshop is to bring together the fundamental physics, quantum sensor, and space instrument communities in order to brainstorm ideas for space missions with quantum sensors that can shed light on physics beyond the Standard Model. For more information, please see our conference website:
https://sites.google.com/view/fundamental-physics-in-space
We hope that you will join us for the workshop! Please also forward this message to colleagues and team members who may be interested, especially postdocs and graduate students who are not on this email list.
All interested participants must apply to attend the workshop through the ACP website:
https://aspenphys.org/winter/winter-application-process
The application portal is open now, and applications must be submitted before the portal closes on September 15. Contributed talks and posters are encouraged.
Call for Abstracts: ITM/PTTI 2026
Abstract Deadline is October 3, 2025
Submit your abstract today for the ITM/PTTI 2026 conference. The ION International Technical Meeting (ITM) features a technical program related to positioning, navigation and timing and includes the ION Fellows and Annual Awards presentations. The meeting will take place in Anaheim, California, January 26-29, 2026, and will be co-located with the Precise Time and Time Interval Systems and Applications Meeting (PTTI).
Two Technical Events for the Price of One
ITM is the ION’s winter meeting with peer-reviewed technical papers related to positioning, navigation, and timing and includes the ION Fellows and Annual Awards presentations.
PTTI is the technical conference designed to disseminate and coordinate PTTI information at the user level; review present and future PTTI requirements; inform government and industry engineers, technicians and managers of precise time and frequency technology and its problems; and provide an opportunity for an active exchange of new technology associated with PTTI.
Registration will open in Fall of 2025.
REFIMEVE general meeting 2025 – Grenoble
The next REFIMEVE/T-REFIMEVE general meeting will be held this year on December 1 and 2 in Grenoble.
The program is currently being finalized, but the outline will be as follows:
December 1 – opening at 2 p.m., followed by scientific presentations and a poster session.
December 2 morning – scientific presentations.
December 2 afternoon – lab visits and poster session (continued).
Please reserve these dates now.
