Absence of self-averaging in the complex admittance for transport through disordered media
Mitsuhiro Kawasaki, Takashi Odagaki, Klaus W. Kehr
Random walk models in one-dimensional disordered media with an oscillatory input current are investigated theoretically as generic models of the boundary perturbation experiment. I…
Absence of self-averaging in the complex admittance for transport through random media
Mitsuhiro Kawasaki, Takashi Odagaki, Klaus W. Kehr
A random walk model in a one dimensional disordered medium with an oscillatory input current is presented as a generic model of boundary perturbation methods to investigate propert…
Hopping motion of lattice gases through nonsymmetric potentials under strong bias conditions
K. W. Kehr, Z. Koza
The hopping motion of lattice gases through potentials without mirror-reflection symmetry is investigated under various bias conditions. The model of 2 particles on a ring with 4 s…
Connection between Dispersive Transport and Statistics of Extreme Events
K. W. Kehr, K. P. N. Murthy, H. Ambaye
A length dependence of the effective mobility in the form of a power law, B ~ L^(1-1/alpha) is observed in dispersive transport in amorphous substances, with 0 < α< 1. We deduce th…
Toy model for molecular motors
H. Ambaye, K. W. Kehr
A hopping model for molecular motors is presented consisting of a state with asymmetric hopping rates with period 2 and a state with uniform hopping rates. State changes lead to a…
Single-Particle Diffusion-Coefficient on Surfaces with Ehrlich-Schwoebel-Barriers
K. Mussawisade, T. Wichmann, K. W. Kehr
The diffusion coefficient of single particles in the presence of Ehrlich-Schwoebel barriers (ESB)is considered. An exact expression is given for the diffusion coefficient on linear…
Diffusion Coefficients of Single and Many Particles in Lattices with Different Forms of Disorder
K. W. Kehr, T. Wichmann
A survey is given on asymptotic diffusion coefficients of particles in lattices with random transition rates. Exact and approximate results for single particles are reviewed. A rec…
