Nonlinear Dynamics and Control

Lupe [1]

Prof. Dr. Dr. h.c. Eckehard Schöll, PhD [2]
In the center of the activities of the group are theoretical investigations and computer simulations of nonlinear dynamic systems and complex networks. We study self-organized spatio-temporal pattern formation and its control by time-delayed feedback methods, and stochastic influences and noise. Our current research focusses on the deliberate control and selection of complex, chaotic, or noise-induced space-time patterns as well as dynamics of complex delay-coupled networks. As state-of-the-art applications we investigate power grids, optoelectronic and neural systems, in particular neuronal network dynamics, semiconductor lasers, and nonlinear dynamics in semiconductor nanostructures.
Eckehard Schöll is, besides his affiliation with TU Berlin, a member and Principal Investigator of the Bernstein Center for Computational Neuroscience Berlin (since 2010) and a guest scientist at the Potsdam Institute for Climate Impact Research (since 10/2020). He is President of the International Physics and Control Society (IPACS).
