Percolation model for a selective response of the resistance of composite semiconducting np-systems towards reducing gases
Stefanie Russ
It is shown that a two-component percolation model can explain an experimentally observed behavior, namely that a network built up by a mixture of sintered nanocrystalline semicond…
Ising-like dynamics and frozen states in systems of ultrafine magnetic particles
Stefanie Russ, Armin Bunde
We use Monte-Carlo simulations to study aging phenomena and the occurence of spinglass phases in systems of single-domain ferromagnetic nanoparticles under the combined influence o…
Pore opening effects and transport diffusion in the Knudsen regime in comparison to self- (or tracer-) diffusion
S. Zschiegner, S. Russ, A. Bunde +1
We study molecular diffusion in linear nanopores with different types of roughness in the so-called Knudsen regime. Knudsen diffusion represents the limiting case of molecular diff…
Frozen metastable states in ordered systems of ultrafine magnetic particles
Stefanie Russ, Armin Bunde
For studying the interplay of dipolar interaction and anisotropy energy in systems of ultrafine magnetic particles we consider simple cubic systems of magnetic dipoles with anisotr…
Application of the Trace Formula in Pseudointegrable Systems
Stefanie Russ, Jesper Mellenthin
We apply periodic-orbit theory to calculate the integrated density of states from the periodic orbits of pseudointegrable polygon and barrier billiards. We show that the res…
Periodic orbit theory in fractal drum
Stefanie Russ, Jesper Mellenthin
The level statistics of pseudointegrable fractal drums is studied numerically using periodic orbit theory. We find that the spectral rigidity , which is a measure for the c…
