The group is focused on multi-scale atomistic simulations of materials with particular focus on nanosystems. Specifically, we carry out calculations of the mechanical, magnetic and opto-electonic properties of materials at various levels of sophistication ranging from time-dependent density functional theory to empirical potential molecular dynamics and kinetic Monte-Carlo methods. We also study effects of ion and electron irradiation on solids.
Effects of ion and electron irradiation on two-dimensional (2D) materials such as graphene and transition-metal dichalcogenides.
The Group Leader is also a Vising Scientist at DTU, Denmark (Otto Mønsted Guest Professor) and at the Aalto University, Finland.
The group works in collaborations with the experimental groups at the Ion Beam Center (HZDR), and also has numerous external coworkers in Germany (University of Köln, University of Ulm, University of Duisburg-Essen, Technical University of Dresden), Finland (Aalto University, University of Helsinki), Japan (AIST, NIMS) and Denmark (DTU).
