C06: Driven activation in a nonequilibrium bath

Funding period: 2021 – 2024 

Project leader: Matthias Fuchs

Scientific staff: Nikolas Ditz, Saswati Ganguly, Stefan Gerlach

The activated crossing of an energy barrier is a ubiquitous dynamical process in materials, yet activation far from thermal equilibrium and in high dimensional energy landscapes remains poorly understood. The project will develop a theoretical framework for studying the spectroscopy of intramolecular fluctuations of a bistable probe particle in a flowing fluid or deforming amorphous solid. The conditions for observing activated dynamics in the nonlinear (double-well) potential coupled to the driven particulate bath will be investigated from first principles and the concepts of mechanical noise and effective temperature scrutinized.
