How graphene sheets respond to force
Bogdan and Frauke have published two back-to-back articles (one together with the former member of the MBM group Dr. Ilona Baldus) studying the force and stress distribution in a sheet of graphene indented by an Atomic Force Microscopy tip until rupture. They developed a new potential to model the carbon-carbon bond breaking in a simple and efficient, yet realistic way. Using it in simulations of up to several million atoms, they closely reproduce experimental result of graphene rupture and find a highly focused mechanical stress to be the cause of material failure.

In a number of projects, FDA also helped to reveal the mechanism of allostery in proteins. More details are given here.
About HITS
HITS, the Heidelberg Institute for Theoretical Studies, was established in 2010 by physicist and SAP co-founder Klaus Tschira (1940-2015) and the Klaus Tschira Foundation as a private, non-profit research institute. HITS conducts basic research in the natural, mathematical, and computer sciences. Major research directions include complex simulations across scales, making sense of data, and enabling science via computational research. Application areas range from molecular biology to astrophysics. An essential characteristic of the Institute is interdisciplinarity, implemented in numerous cross-group and cross-disciplinary projects. The base funding of HITS is provided by the Klaus Tschira Foundation.
