Phonons in aperiodically ordered layer systems

Surface Science, 2008
Abstract We have studied the phonons in multilayer structures following different aperiodic sequences (Fibonacci, Thue–Morse, Period-Doubling) along the growth direction. We have employed a nearest-neighbor force constant model giving a reasonably realistic description of metal systems.

The role of aperiodic order in science and technology

Reports on Progress in Physics, 2005
In this work we consider the role of aperiodic order in different domains of science and technology from an interdisciplinary approach. To start with, we introduce some general classification schemes for aperiodic arrangements of matter. Afterwards, we review the main physical properties and possible applications of quasiperiodic crystals.

Kolakoski sequences – an example of aperiodic order

Journal of Non-Crystalline Solids, 2004
Abstract (Generalized) Kolakoski sequences are built of two symbols – similar to the Fibonacci-chain – and can be constructed by a very simple rule. They are general enough to allow a richness of structures: e.g., some show pure point diffraction spectrum, others diffuse scattering.
