Missions
A post-doctoral position is available at the ICB Laboratory (Dijon, France) from January 1, 2025. The aim is to model ultracold gases composed of lanthanide and alkali-metal atoms, and in particular their collisional properties (Feshbach resonances). The results obtained will be compared with experimental measurements. Discussions with experimental colleagues will therefore be an important part of the work. The results obtained will be published as articles in peer-reviewed journals and presented at national and international conferences.
Activities
Using quantum collision theory, the future post-doc will calculate spectra of Feshbach resonances between pairs of lanthanide and lanthanide-alkali atoms, as a function of various parameters such as temperature. These collisional calculations will involve the characterization of interactions between atoms over a wide range of interatomic distances. The calculated Feshbach resonance spectra will be compared with experimental measurements, providing information on the interactions between pairs of atoms and allowing them to be adjusted. The existing computer codes needed for this modeling will have to be adapted to the problem at hand.
Skills
The successful candidate will have a PhD in theoretical atomic and molecular physics, with a strong background in atomic structure, collision theory and atomic interactions. He/she should also have strong programming skills: Fortran 95 language, parallel programming, working on a computing center. The successful candidate will be expected to work independently, while demonstrating excellent organization and communication skills, in order to bring this project to a successful conclusion.
Work Context
The work will be carried out within the “MARS” team of the ICB Laboratory, possessing recognized expertise in atomic and molecular spectroscopy, as well as in collision theory. In addition, the post-doctoral contract is part of an ANR project starting in January 2025, in collaboration with an experimental team from Collège de France (Paris) and a theoretical team from Laboratoire Aimé Cotton (Orsay). The successful candidate will benefit from the facilities of the Centre de Calcul de l'Université de Bourgogne (CCUB).
The position is located in a sector under the protection of scientific and technical potential (PPST), and therefore requires, in accordance with the regulations, that your arrival is authorized by the competent authority of the MESR.
