A postdoctoral position reserved to applicants with physical disabilities is
available in the theoretical group SIMPA at the laboratory of Physics of Atoms,
Lasers, Molecules and Surfaces in Rennes (France).
Project title is "Theoretical study of reactions in a helium droplet"
Description of project:
Within the family of aggregates, objects between the gaseous and the solid phase,
helium aggregates present fascinating features (low temperatures (380 mK),
superfluidity, huge capture cross section, .... ) which make them popular 'nanoscale
laboratories' for precise spectroscopic studies of different trapped molecules
[Toennies et Vilesov, Angew. Chem. Int. Ed. 2004, 43, 2622]. Use of these aggregates
for studying reaction dynamics, suggested since the initial experiments, is now an
emerging experimental domain which needs parallel theoretical efforts.
In the gaseous phase molecular collisions have been studied and well understood for
several species. However, a collision between two particles is indeed very different in
gaseous phase than on a droplet. Study of collisions in these conditions may provide
additional information both on the collision dynamics and on droplet properties. Moreover,
dependence of molecular dynamics in a droplet on the initial quantum state should open
up novel possibilities of controlling collisions.
The project leans on a twofold expertise of our group : i) quantum dynamics (atom-atom
and atom-molecule) of inelastic and reactive collisions and ii) quantum Monte-Carlo
methods for the determination of ro-vibrational spectra of molecules trapped in helium
nanodroplets.
The applicant will be involved in the study two kind of processes : formation of cold
polar molecules via chemical reaction between excited alkali atoms and hydrogen molecules
on the droplet (e.g. Li* + H2 --> LiH + H) and controlled synthesis of silicium
nanoparticles of interest in optoelectronics.
The candidate should have a solid doctoral or post-doctoral formation either in the domain
of molecular quantum dynamics or in quantum statistical methods. Skills in numerical
programming and simulation are very appreciated.
The position is funded for at least one year by CNRS with monthly allowance of 2 500 EU.
Deadline for application is April 30th.
