The candidate will work in collaboration between the theory group (at LERMA) led by Dr A. Ciardi and the experimental (using high-power lasers) group (at LULI) lead by Dd J. Fuchs. The projects the candidate will work on encompass several areas investigated by our groups: particle acceleration processes in magnetized plasmas, magneto-hydrodynamic instabilities, shock formation and dissipation, collisionless beam/plasma energy transfer. The proposed postdoctoral position will provide numerical modeling support to the experiments conducted within these projects. Several PhDs students are also part of the project and the candidate is expected to participate to their mentoring. The candidate will also be encouraged to write her/his own proposals to advance the projects.
The research work will help design and interpret the experiments by means of two simulation techniques: (i) hybrid-particle-in-cell (PIC) calculations, describing semi-collisional and collisionless interactions; (ii) MHD simulations. PIC simulations will be performed using the existing code HECKLE and presently developed code PHARE. The MHD simulations will be carried out with the high energy density MHD code GORGON. Besides conducting and analyzing high-performance numerical simulations, the postdoctoral fellow is expected to develop dedicated tools and/or improve the simulation codes at his disposal, for example by implementing new physical models or advanced numerical schemes. The candidate is expected to take the lead in writing original papers in high-impact journals highlighting her/his research, relevant to laboratory astrophysics.
A PhD in computational plasma physics, applied mathematics or a related field is required. Fluency in English and a demonstrated ability in scientific paper write-up is necessary, proposal write-up skills is a plus. The candidate is expected to publish and promote her/his research, as well as to propose projects. The project is performed in a team, including strong interactions with the experimental team, hence aptitude for working in a team and in a multi-disciplinary environment is necessary. Other essential criteria for this post are the ability to work independently, organisational ability and ability to account for one's own actions.
The candidate will work in collaboration between the LERMA (https://sites.google.com/site/andreaciardihomepage/home) theoretical and numerical group, and the LULI/SPRINT experimental group (https://portail.polytechnique.edu/luli/fr/personnel/equipes-de-recherche/equipe-sources-de-particules-rayonnement-intenses). The aim of the collaboration is to investigate magnetized plasma dynamics, collisional as well as collisionless ones, with the application to investigate in the laboratory astrophysical phenomena ranging from hydrodynamic instabilities to particle acceleration.
