Missions

- Code development to address specific problems (e.g., numerical solutions to the Schrödinger equation, FDTD calculations, etc.)
- Optimization of computational codes for new architectures
- Implementation of analysis and high-performance computing methods to meet research needs and exploit data from atomic physics experiments conducted by the "Optics and Atomic Interferometry" team at LPL
- Ensure documentation, maintenance, and dissemination of the developed methods and tools
- Deliver presentations and training sessions to facilitate knowledge and skill transfer

Activités

The recruited person will contribute to the development and optimization of computational codes aimed at extracting relevant information from the atomic diffraction signals obtained experimentally. Indeed, the observable measured—the atomic diffraction pattern—serves as an indirect signature of Casimir-Polder forces. Such forces are at the core of the team's research activities. To effectively analyze and interpret the experimental data, robust theoretical and numerical support are essential.

The numerical techniques to be implemented will be diverse, including, for instance, differential calculations, matrix computations, and FDTD simulations in the sub-wavelength regime. The selected candidate will also participate in the analysis and exploitation of the experimental data.

Integrated to the OIA team, the recruited person will contribute to these new developments. This work will be carried out in close collaboration with the Leibniz University of Hanover (Institut für Quantenoptik). Additionally, the candidate will have the opportunity to collaborate with other international teams working alongside the OIA team. This project is interdisciplinary in nature and is part of an international research collaboration framework.

Compétences

- Numerical modeling and simulation
- Drafting user documentation
- Excellent teamwork skills are required
- Candidates must be fluent in English to participate in internal and external communication activities
- General knowledge of atomic interferometry and Casimir-Polder interactions will be appreciated.

Contexte de travail

This project will be conducted at the Laser Physics Laboratory, a joint research unit of Sorbonne Paris Nord University and the CNRS, within the Atomic Optics and Interferometry team (OIA group; see https://www.lpl.univ-paris13.fr/recherche/optique-et-interferometrie-atomiques-oia). It is part of the ANR LIGRINT project. The team comprises a CNRS researcher, a professor, a maître de conférence, and a doctoral student.

Contraintes et risques

The work takes place at the Laser Physics Laboratory, following a full-time schedule from Monday to Friday during daytime hours. It is essential to adhere strictly to standard safety protocols, given the inherent risks associated with the laboratory environment, particularly those related to laser use.
