Postdoc or engineer position for LISA data preprocessing at SYRTE, Paris
The LISA (Laser Interferometer Space Antenna) space mission will allow the detection of low frequency gravitational waves. In this project, we will develop new methods to reduce various noises in the LISA data efficiently in order to detect gravitational waves and to extract scientific results for various types of sources. This position is devoted either to a researcher or to a software engineer. Strong skills in software development, data analysis, and numerical calculations are required. In addition, knowledge of the LISA mission and of its instruments will be favoured. This project will be conducted within the “Theory and metrology” group at SYRTE.
Starting date:
Duration: 1 year ( )
POST-DOC OFFER at FEMTO-ST– Besançon, France
Development of a stabilized laser on a sub-Kelvin Fabry-Perot cavity
Laboratory: FEMTO-ST– Besançon, France
Summary: Ultra-stable lasers have a central role in numerous scientific experiments for high precision measurements: atomic spectroscopy, diffusion of time & frequency signals by optical fiber, detection of gravitational waves and dark matter research. The performances are currently reaching fractional frequency stabilities below 10-16 at 1 second of integration. However, it is still insufficient for many applications including fundamental physics tests and optical atomic clocks. To overcome the current limits, the proposed offer consists in studying as finely as possible the behavior of a Fabry-Pérot cavity at 1 K, which will be used to stabilize a laser in frequency.
Offer details:
- Prerequisites : PhD in Physics
- Desired skills: Optical frequency metrology, Gaussian optics in free-space, Analog, digital and radio-frequency electronics, Control theory and locking/feedback techniques, Instrumentation, Cryogenic and ultra-high vacuum, Analysis and interpretation of noise and sources of noises
- Contract duration : 1 year
- Salary : approximately €2300 net
- Procedure : Send CV, cover letter and at least 1 reference letter to jonathan.gillot@femto-st.fr.
Research engineer with expertise in instrumentation
Post-doctorate position : Hydrogen deceleration for its first observation of the Gravitational Quantum States
This project aims to perform the first observation of Gravitational Quantum States on
hydrogens in flight. This experiment is part of the international collaboration GRASIAN: GRAvity Spectroscopy and Interferometry with ultra-cold Atoms and Neutrons (https://grasian.eu).
Full time post–doctorate, mainly experimental position. 12 months contract (possibility of extension).
Start date: February 2024 – January 2025.
Location: Laboratoire Kastler Brossel, Sorbonne Université, CNRS, ENS, Collège de France. 4 place Jussieu, 75005 Paris
Assistant professor position, Sorbonne Université, SYRTE laboratory, Paris (section 30).
The Systèmes de Référence Temps-Espace (SYRTE) laboratory carries out research in the field of fundamental astronomy, time and frequency metrology and sensor, and history of astronomy. A pioneering institution in their deveopment, it studies different types of cold-atom-based quantum sensors: microwave clocks, optical clocks and inertial sensors (gyrometers, gravimeters, gradiometers, chip-scale interformeters). These sensors have demonstrated a remarkable efficiency for realizing measurement instruments of unprecedented performances, for innovative applications in different disciplinary fields: geophysics, fundamental metrology, tests of fundamental laws of physics, positionning and navigation. In order to overcome sensitivity limits of these sensors, or improve their compactnes to turn them into transportable devices, it is important to utilize ressources offered by quantum mechanics, which have been, so far, little exploited for space-time measurement. These protocols include, as exemples, optimal quantum control, non-demolition measurement and preparation of squeezed states for measurement beyond the standard quantum limit, or even entanglement between different sensors. The SYRTE laboratory wants to hire an Assistant Professor in quantum physics to work in the specific domain of quantum protocoles applied to cold atoms sensors, in order to improve their limits in terms of sensitivity, and strengthen its position in ahighly competitive domain at the international scale.
