Comment on `Formation of a Dodecagonal Quasicrystalline Phase in a Simple Monatomic Liquid'
J. Roth
In a recent paper M. Dzugutov, Phys. Rev. Lett. 70 2924 (1993), describes a molecular dynamics cooling simulation where he obtained a large monatomic dodecagonal quasicrystal from…
Random tiling quasicrystals in three dimensions
W. Ebinger, J. Roth, H. -R. Trebin
Three-dimensional icosahedral random tilings with rhombohedral cells are studied in the semi-entropic model. We introduce a global energy measure defined by the variance of the qua…
Random Tiling Transition in Three Dimensions
W. Ebinger, J. Roth, H. -R. Trebin
Three-dimensional icosahedral random tilings are studied in the semi-entropic model. We introduce a global energy measure defined by the variance of the quasilattice points in orth…
Icosahedral coincidence rotations
Johannes Roth, Reinhard Lück
The coincidence problem for three-dimensional discrete structures with icosahedral symmetry is reinvestigated. We present a parametric description of the coincidence rotations base…
Atomic Self-Diffusion in Quasicrystals: A Molecular Dynamics Study
Johannes Roth, Franz Gaehler
We present a molecular dynamics study on atomic self-diffusion in Frank-Kasper type dodecagonal quasicrystals. It is found that the quasicrystal-specific flip mechanism for atomic…
A new binary decagonal Frank-Kasper quasicrystal phase
Johannes Roth, Christopher L. Henley
A structure model of atoms of two sizes, interacting with Lennard-Jones potentials and simulated by molecular dynamics, was observed to freeze into a decagonal quasicrystal dominat…
