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…

Structure factors of harmonic and anharmonic Fibonacci chains by molecular dynamics simulations
Michael Engel, Steffen Sonntag, Hansjörg Lipp +1
The dynamics of quasicrystals is characterized by the existence of phason excitations in addition to the usual phonon modes. In order to investigate their interplay on an elementar…
