Intermittency induced long-range cross-correlations
Fotis K. Diakonos, Alexandros K. Karlis, Peter Schmelcher
Cross-correlations are usually considered to emerge through interaction between particles. Here we present a mechanism capable to generate power-law cross-correlations between non-…
Critical non-equilibrium steady states of the Lorentz channel
Alexandros K. Karlis, Fotios K. Diakonos, Christoph Petri +1
We investigate the transport properties of non-interacting particles propagating in a finite Lorentz channel (LC). We show that interparticle power-law correlations emerge, when th…
A consistent approach for the treatment of Fermi acceleration in time-dependent billiards
A. K. Karlis, F. K. Diakonos, V. Constantoudis
The standard description of Fermi acceleration, developing in a class of time-dependent billiards, is given in terms of a diffusion process taking place in momentum space. Within t…
Scattering off an oscillating target: Basic mechanisms and their impact on cross sections
I. Brouzos, A. K. Karlis, C. A. Chrysanthakopoulos +4
We investigate classical scattering off a harmonically oscillating target in two spatial dimensions. The shape of the scatterer is assumed to have a boundary which is locally conve…
Hyperacceleration in a stochastic Fermi-Ulam model
A. K. Karlis, P. K. Papachristou, F. K. Diakonos +2
Fermi acceleration in a Fermi-Ulam model, consisting of an ensemble of particles bouncing between two, infinitely heavy, stochastically oscillating hard walls, is investigated. It…
