We have studied the influence of a particular kind of phason-defect on the Landauer resistance of a Fibonacci chain. Depending on parameters, we sometimes find the resistance to decrease upon introduction of defect or temperature, a behavior that also appears in real quasicrystalline materials. We demonstrate essential differences between a standard tight-binding model and a full continuous model. In the continuous case, we study the conductance in relation to the underlying chaotic map and its…

Electronic transport properties of quasicrystals
We present a review of some results concerning electronic transport properties of quasicrystals. After a short introduction to the basic concepts of quasiperiodicity, we consider the experimental
A Search for the Predicted Magnetic 5d Surface Atoms W and Re
The magnetism of the 5d metals W and Re is investigated with the method of weak localization. We studied W on the surface of Au and Re on the surface of Ag. For both systems the impurity thicknesses
Dynamics and Transport Properties of Aperiodic Crystals
The physical properties o aperiodic, but well ordered systems as incommensurate crystal phases and quasicrystals, are in many respects different from those of lattice periodic structures. The usual
Topological Proximity Effect: A Gauge Influence from Distant Fields on Planar Quantum-Coherent Systems
A quantum system that lies nearby a magnetic or time-varying electric field region, and that is under periodic boundary conditions parallel to the interface, is shown to exhibit a “hidden”
Electronic Conductivity of Quasicrystals and Approximants
From rigorous mathematical developments to extensive numerical calculations in realistic models of periodic approximants or 3D quasiperiodic systems, anomalous diffusion has been clearly connected
States on the Sierpinski Triangle
States on a Sierpinski triangle are described using a formally exact and general Hamiltonian renormalization. The spectra of new (as well as previously examined) models are characterized. Numerical
Analyzing results of impedance spectroscopy using novel evolutionary programming techniques
This paper discusses the application of evolutionary programming methods to the problem of analyzing impedance spectroscopy results, and two complementary methods have been applied: Genetic Algorithm and Genetic Programming (GP).
Vibrations of simple fractal-based models
Dynamical systems with fractal geometry can be constructed in a variety of ways: We illustrate this variety with examples based on the Cantor set, the Sierpinski gasket, and on lattices of these
