Freely forming groups: Trying to be rare
Michael Baake, Uwe Grimm, Harald Jockusch
A simple weakly frequency dependent model for the dynamics of a population with a finite number of types is proposed, based upon an advantage of being rare. In the infinite populat…
Multiscaling, Ergodicity and Localization in Quasiperiodic Chains
V. Z. Cerovski, M. Schreiber, U. Grimm
We report results of numerical simulations of wave-packet dynamics in a class of chains consisting of two types of weakly coupled clusters arranged in a quasiperiodic sequence. Pro…
Spectral and Diffusive Properties of Silver-Mean Quasicrystals in 1,2, and 3 Dimensions
V. Z. Cerovski, M. Schreiber, U. Grimm
Spectral properties and anomalous diffusion in the silver-mean (octonacci) quasicrystals in d=1,2,3 are investigated using numerical simulations of the return probability C(t) and…
Noncollinear magnetic order in quasicrystals
E. Y. Vedmedenko, U. Grimm, R. Wiesendanger
Based on Monte-Carlo simulations, the stable magnetization configurations of an antiferromagnet on a quasiperiodic tiling are derived theoretically. The exchange coupling is assume…
