Granular flow modelled by Brownian particles
T. L. Riethmueller, D. Rosenkranz, L. Schimansky-Geier
Granular flows through pipes show interesting phenomena, e.g. clogging and density waves, 1/f-noise. These things are fairly good studied by computer-experiments, but there is a la…
Collective Motion due to escape and pursuit response
Pawel Romanczuk, Iain D. Couzin, Lutz Schimansky-Geier
Recent studies suggest that non-cooperative behavior such as cannibalism may also be a driving mechanism of collective motion. Motivated by these novel results we introduce a simpl…
Surmounting collectively oscillating bottlenecks
D. Hennig, L. Schimansky-Geier, P. Hänggi
We study the collective escape dynamics of a chain of coupled, weakly damped nonlinear oscillators from a metastable state over a barrier when driven by a thermal heat bath in comb…
Slowly rocking symmetric, spatially periodic Hamiltonians: The role of escape and the emergence of giant transient directed transport
D. Hennig, L. Schimansky-Geier, P. Hänggi
The nonintegrable Hamiltonian dynamics of particles placed in a symmetric, spatially periodic potential and subjected to a periodically varying field is explored. Such systems can…
