Duration: 15 months (ANR funding)
Starting date: September 1st, 2025
The Magnetic Quantum Gases (GQM) group of LPL offers a postdoctoral position in the field
of dipolar quantum gas experiment using chromium atoms. Magnetic atoms, which can be
loaded in optical lattices in a low-entropy state, provide a highly relevant platform for the study
of quantum magnetism. The host team studies out-of-equilibrium dynamics of long-range
interacting spin systems, and in particular seeks to measure the development of entanglement
linked to the phenomenon of quantum thermalization. The person recruited will first contribute to the assembly of the new UHV experiment chamber, and to the installation of the new laser cooling and trapping system. He/she will play a leading role in obtaining a BEC, then in loading it into an optical lattice, and will set up the new tools the team has planned in order to obtain new results on the physics of interacting N-body systems: adaptive optics, in order to explore new trapping geometries; in-vacuum RF coils to better control RF transitions; measurement of the magnetic field close to the atoms by
spectroscopy.
Two teacher-researchers, a CNRS researcher, and a CNRS research engineer are involved in
the project. We have established fruitful collaborations with theorists for the interpretation of
our results.
Profile and skills required:
The candidate must have a solid experience in cold atoms experiment, in particular in optics
and light-matter interactions
