Postdoc: Reactive scattering with electronic friction
Offer DescriptionThe Faculty of Science Leiden and Leiden Institute of Chemistry are looking for a postdocReactive scattering with electronic friction
The project revolves around recent work in Jörg Meyer’s group on non-adiabatic effects on reactive scattering of small molecules on metal surfaces [1-3]. Even in the weakly non-adiabatic regime, electron-hole pair excitations in the metal surface can have a pronounced effect on the dissociative chemisorption probabilities depending on how electronic friction coefficients are determined [1,2]. In this project, these insights are to be extended towards other incident conditions, i.e., mainly higher incidence energies, which requires the development and implementation of a new machine-learning model to represent the tensorial electronic friction coefficients of (diatomic) molecules. Despite of its very fundamental scientific character this work is of interest to a large industrial partner with whom we have established an extensive collaboration. It is going to be embedded in our team of theoretical and computational both chemists and physicists in the Theoretical Chemistry group, providing opportunities to learn from each other and a lot of potential for collaboration(s). Thanks to our access to considerable computational resources both in house and at the national level, computing time is not expected to be a bottle neck.[1] N. Gerrits, J. I. Juaristi, and J.

The successful candidate has well-developed and programming skills in Python and at least one other “fast” programming language (in particular Fortran or C) – proven by the candidate’s PhD or other previous projects. These skills are essential for the development and implementation of a new machine-learning model to represent the tensorial electronic friction coefficients of (diatomic) molecules on metal surfaces. Ideally, the candidate also has prior knowledge about machine learning and its applications in its nowadays typical applications in computational chemistry.Additional selection criteria:
