Stationary phases and dynamic activation in parametrically-driven stochastic resonators (C08)

• Subject Area: Theoretical Condensed Matter Physics
• Term: since 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 425217212

Thermally activated transition rates between metastable states in complex energy landscapes are the basis for many phenomena in physics, chemistry and biology. In this theoretical project, we study such noise activation dynamics in nonlinear resonator systems subject to parametric drives, i.e., in a deep out-of-equilibrium setting. The interplay between the time-dependent drives and system nonlinearities leads to different oscillation responses that manifest in a rotating picture as metastable states in quasienergy potential landscapes. This project brings in a unique scientific frontier to the CRC, involving fundamental research of fluctuations in out-of-equilibrium nonlinear parametron networks, while harboring a potential application for harnessing these systems as analog annealers for solving optimization problems.
