Paradigm of stochastic resonance: A symmetric double-well potential is periodically rocked by a weak driving signal. The presence of an optimal dose of noise will statistically induce synchronized hopping events between the two wells.
Our main emphasis is on monostable systems, on quantum mechanical phenomena, and, in particular, on collective phenomena in colloidal systems within a collaboration with the experimental group of Clemens Bechinger at the University of Stuttgart.
The methodological basis for this research is provided by our projects on
noise-induced collective phenomena ,
decay of complex metastable states,
open quantum systems.
