Junior Professor Chair PRECISION – Precision Measurements for Fundamental Physics
Host Institution: Laboratoire Kastler Brossel
Lead Institution: CNRS
Host Laboratory: Laboratoire Kastler Brossel (LKB)
This position is also open at Laboratoire Aimé Cotton (LAC) and Laboratoire de Physique des Lasers (LPL).
Duration: 6 years, with the possibility of obtaining a permanent position as Director of Research at CNRS, following evaluation of scientific merit and professional competence by a tenure commission.
Salary: Minimum gross monthly salary of €3,443.50 (as set by official decree).
Accompanying Budget: €200K
The Laboratoire Kastler Brossel (LKB) is a major research center in quantum physics, recognized for its expertise in quantum metrology, atomic interferometry, and high-resolution spectroscopy of simple, exotic, and trapped ion systems. LKB is actively involved in large-scale projects and international collaborations, including GBAR and LIGO-Virgo.
Position Objectives
The selected candidate will lead an ambitious research project with the overarching goal of pushing the sensitivity limits of low-energy experiments to explore the fundamental laws of the Universe and test the Standard Model.
Scientific Project
The candidate will have full freedom to propose a groundbreaking, internationally competitive experimental research project at the cutting edge of fundamental physics. The project should leverage the unique properties of ultracold atoms and molecules, trapped ions, and recent advancements in quantum control and atomic interferometry. These approaches, while not exhaustive, may be combined to further extend the precision limits of experimental measurements.
Potential research topics include (but are not limited to):
Determination and investigation of variations in fundamental constants
Study of fundamental symmetries
Measurement of the electron’s electric dipole moment
Exploration of alternative theories, particularly those aiming to unify quantum mechanics and gravity
Development of state-of-the-art technologies for large-scale atomic interferometers, with the sensitivity required for gravitational wave detection
Teaching Responsibilities
28 hours of lectures or 42 hours of practical or tutorial sessions, related to the research themes of the junior professor chair.
Topics may cover both fundamental aspects—such as the quantum control of atomic and molecular systems—and technical aspects, such as noise source analysis and laser frequency stabilization techniques.
