JOUW FUNCTIE

We invite applications for a PhD position to advance diagrammatic many-body perturbation theory for single- and two-body Green’s functions to describe charged and neutral excited states of molecules with quantitative accuracy. Building on on-going work in our group(1–3), the project aims to systematically assess the impact of state-of-the-art vertex corrections to fully self-consistent GW within Hedin’s equations. The main goals are to account for dynamical screening in the vertex, going beyond first-order vertex corrections, and designing efficient schemes to embed vertex-corrected GW within low-order perturbation theory. The project combines theoretical work, algorithm development, and efficient implementation into a modern electronic structure code. It offers an opportunity to contribute to fundamental advances in many-body theory with direct applications in quantum chemistry and electronic structure theory.
The successful candidate will join the quantum chemistry group at the Vrije Universiteit Amsterdam and be supervised by dr. Arno Förster. For an overview of our current group and our research interests please check out our group page. We are an interdisciplinary and international group of chemists and physicists working on the development of novel methods in electronic structure theory and their application to molecules and periodic systems. This PhD project offers plenty of space for your personal development, including participation in international summer schools and conferences.
The planned starting date for the PhD is between October 1st and December 1st 2025.
