Generalized Inverse Participation Numbers in Metallic-Mean Quasiperiodic Systems
Stefanie Thiem, Michael Schreiber
From the quantum mechanical point of view, the electronic characteristics of quasicrystals are determined by the nature of their eigenstates. A practicable way to obtain informatio…
Wave Functions, Quantum Diffusion, and Scaling Exponents in Golden-Mean Quasiperiodic Tilings
Stefanie Thiem, Michael Schreiber
We study the properties of wave functions and the wave-packet dynamics in quasiperiodic tight-binding models in one, two, and three dimensions. The atoms in the one-dimensional qua…
Renormalization Group Approach for the Wave Packet Dynamics in Golden-Mean and Silver-Mean Labyrinth Tilings
Stefanie Thiem, Michael Schreiber
We study the quantum diffusion in quasiperiodic tight-binding models in one, two, and three dimensions. First, we investigate a class of one-dimensional quasiperiodic chains, in wh…
Wave Packet Dynamics, Ergodicity, and Localization in Quasiperiodic Chains
Stefanie Thiem, Michael Schreiber, Uwe Grimm
In this paper, we report results for the wave packet dynamics in a class of quasiperiodic chains consisting of two types of weakly coupled clusters. The dynamics are studied by mea…
