Dynamics of particle flips in two-dimensional quasicrystals
Michael Engel, Masahiro Umezaki, Hans-Rainer Trebin +1
The dynamics of quasicrystals is more complicated than the dynamics of periodic solids and difficult to study in experiments. Here, we investigate a decagonal and a dodecagonal qua…

Phason Dynamics in One-Dimensional Lattices
Hansjörg Lipp, Michael Engel, Steffen Sonntag +1
In quasicrystals, the phason degree of freedom and the inherent anharmonic potentials lead to complex dynamics which cannot be described by the usual phonon modes of motion. We hav…
