Theory days on Ultrafast processes in molecules and clusters (Meeting / LPT), 23-25/11/2022

23 November 2022; 9h00 - 25 November 2022; 17h00

Organizers : M. Belkacem,P. M. Dinh, E. Suraud, N. Tancogne-Dejean

Aim and objectives

Following the tradition of the previous successful meetings that have started in 2009, the Theory Days workshop aims at stimulating constructive discussions, collaborations, and knowledge exchange among a selected group of theoreticians. This year, the fourteenth edition will be dedicated to Ultrafast processes in molecules and clusters.

The workshop will be dedicated to numerical approaches for Ultrafast (UF) phenomena in clusters and molecules following a laser irradiation or a collision with a swift ion. It is now possible to generate laser pulses down to the attosecond domain (10^-18 s) which opens the door to time resolved analysis of system’s response now at the electronic level. Similar time scales are attained with swift projectiles, which raises interesting questions in the general field of irradiation.

Such UF processes underlie numerous physical phenomena which require dedicated analysis, both experimentally and theoretically. We shall focus discussions on how to access to system’s properties from a theoretical viewpoint, which in particular implies a proper choice of relevant observables accessible both experimentally and theoretically.

The aim of the meeting is twofold. We shall discuss possible solutions to develop in order to properly describe UF processes and identify pending underlying problems. We shall also, in the continuity of last year edition of Theory Days on High Performance Computing start to analyse benchmarking results stemming from comparisons between various simulation packages.

The workshop will gather people from various groups working in this domain, mostly in western Europe. The workshop is intended to be a working forum, thus rather informal. The format will consist in a series of long detailed talks, typically 1 hour (40 mn talk + 10 mn for questions) focusing in particular on ongoing problems and open issues.
