Research Position (Postdoc) (m/f/d)

• Start: as soon as possible
• Vergütung: salary according to Remuneration level 13 TV-L
• Umfang: Vollzeit
• Befristung: befristet ((2 years))
• Arbeitsort: Bielefeld

Prof. Dr. Malte Rösner’s group studies the properties of novel correlated quantum materials. A particular focus is on synergistic collaboration with groups in experimental physics. To this end, ab initio calculations are combined with modeling concepts and numerical many-body methods to enable material-specific theoretical predictions.

Ihre Aufgaben

The goal is to develop numerical methods that allow for the material-specific description of (strong) correlation effects in structurally complex systems. To this end, so-called “downfolding” algorithms will be applied and further developed to derive minimal many-body models. Building on this, these models will be analyzed using appropriate numerical treatments (“solvers”) to investigate, among other things, (unconventional) magnetic and/or optical properties of magnetic van der Waals materials and in particular mesoscale engineered CrSBr.

Tasks:

• theoretical scientific work/research on (strongly) correlated materials (95 %)
• participation in self-governance tasks (5 %)

Employment is conducive to scientific qualification and provides the opportunity for further academic development.
