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…
Finite quantum dissipation: the challenge of obtaining specific heat
Peter Hänggi, Gert-Ludwig Ingold, Peter Talkner
We consider a free particle coupled with finite strength to a bath and investigate the evaluation of its specific heat. A harmonic oscillator bath of Drude type with cutoff frequen…
Entropic particle transport in periodic channels
P. S. Burada, G. Schmid, P. Talkner +3
The dynamics of Brownian motion has widespread applications extending from transport in designed micro-channels up to its prominent role for inducing transport in molecular motors…
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…
Steady-State Lévy Flights in a Confined Domain
S. I. Denisov, Werner Horsthemke, Peter Hänggi
We derive the generalized Fokker-Planck equation associated with a Langevin equation driven by arbitrary additive white noise. We apply our result to study the distribution of symm…
Molecular electronics in junctions with energy disorder
Franz J. Kaiser, Peter Hänggi, Sigmund Kohler
We investigate transport through molecular wires whose energy levels are affected by environmental fluctuations. We assume that the relevant fluctuations are so slow that they, wit…
