Missions

The EPAD project – Electron-Positron Attosecond Dynamics in Exotic Systems (funded by the French National Research Agency, ANR JCJC) aims to develop a new theoretical and numerical framework to describe correlated electron–positron dynamics in atoms, and to identify experimentally accessible observables in attoscience.

The postdoctoral researcher will carry out methodological developments and advanced numerical simulations to explore these ultrafast dynamics in exotic systems.

Activities

-Develop and optimize TD-RAS (time-dependent restricted-active-space) methods for many-body systems including positrons.

- Carry out large-scale numerical simulations of photoionization and de-excitation processes (Auger–Meitner decay, positron emission, etc.).

-Identify relevant observables for attosecond pump–probe experiments, in collaboration with theoretical and experimental partners (Sorbonne Université, CNRS, University of Oslo).

-Contribute to the development of open-source software and to the dissemination of results in high-impact international journals and conferences.

Skills

-PhD in atomic and molecular physics, chemical physics, or quantum chemistry.

-Strong experience in numerical methods, electronic structure theory, and/or time-dependent approaches.

-Proficiency in high-performance computing (MPI/OpenMP/GPU) and scientific code development is a plus.

-Interest in attoscience and/or matter–antimatter physics is an asset.

-Ability to work independently in a collaborative and international environment.

Work Context

The postdoctoral researcher will be hosted at LCPMR (Sorbonne Université, Paris), in a dynamic scientific environment internationally recognized for its expertise in attoscience, numerical methods, and modeling. The EPAD project brings together a multidisciplinary team spanning electronic correlation theory, quantum chemistry, experimental attoscience, and antimatter physics.
