Universität Bielefeld
Bielefeld, Nordrhein-Westfalen 33519, Germany
Vollzeit
Reference: 1005620590
Your Tasks
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:
Employment is conducive to scientific qualification and provides the opportunity for further academic development.
