Cooperative surmounting of bottlenecks
D. Hennig, C. Mulhern, L. Schimansky-Geier +2
The physics of activated escape of objects out of a metastable state plays a key role in diverse scientific areas involving chemical kinetics, diffusion and dislocation motion in s…
Nonlinear response of a linear chain to weak driving
D. Hennig, C. Mulhern, A. D. Burbanks +1
We study the escape of a chain of coupled units over the barrier of a metastable potential. It is demonstrated that a very weak external driving field with suitably chosen frequenc…
Directed transport of two interacting particles in a washboard potential
D. Hennig, A. D. Burbanks, A. H. Osbaldestin
We study the conservative and deterministic dynamics of two nonlinearly interacting particles evolving in a one-dimensional spatially periodic washboard potential. A weak tilt of t…
Current control in a tilted washboard potential via time-delayed feedback
Dirk Hennig
We consider motion of an overdamped Brownian particle in a washboard potential exerted to a static tilting force. The bias yields directed net particle motion, i.e. a current. It i…
Resonance-like phenomena of the mobility of a chain of nonlinear coupled oscillators in a two-dimensional periodic potential
S. Martens, D. Hennig, S. Fugmann +1
We study the Langevin dynamics of a two-dimensional discrete oscillator chain absorbed on a periodic substrate and subjected to an external localized point force. Going beyond the…
Self-organized escape of oscillator chains in nonlinear potentials
D. Hennig, S. Fugmann, L. Schimansky-Geier +1
We present the noise free escape of a chain of linearly interacting units from a metastable state over a cubic on-site potential barrier. The underlying dynamics is conservative an…
