Affine Extension of Noncrystallographic Coxeter Groups and Quasicrystals
Unique affine extensions H 2 , H 3 and H 4 are determined for the noncrystallographic Coxeter groups H2, H3 and H4. They are used for the construction of new mathematical models for quasicrystal fragments with 10-fold symmetry. The case of H 2 corresponding to planar point sets is discussed in detail. In contrast to the cutand-project scheme we obtain by construction finite point sets, which gr...
متن کاملAluminium diffusion in decagonal quasicrystals.
Aluminium is the majority element in many quasicrystals and expected to be the most mobile element, but its diffusion properties are hardly accessible to experiment. Here we investigate aluminum diffusion in decagonal Al-Ni-Co and Al-Cu-Co quasicrystals by molecular dynamics simulations, using classical effective pair potentials. Above two-thirds of the melting temperature, strong aluminum diff...
متن کاملAtomic dynamics and diffusion in decagonal quasicrystals
The atomic dynamics of decagonal Al-Ni-Co and Al-Cu-Co quasicrystals is investigated by molecular dynamics simulations. Depending on the local environments, the mobility of the atoms varies greatly from site to site. Above two thirds of the melting temperature, a large fraction of the aluminium atoms become so mobile, that their diffusion can be measured directly in the simulation. As aluminium...
متن کاملCluster Models of Decagonal Tilings and Quasicrystals
Two different relaxed versions of Gummelt’s aperiodic cluster covering rules are considered. These relaxed covering rules produce certain random tiling type structures, which are precisely characterized, along with their relationships to various other random tiling ensembles. One variant of the relaxed covering rules allows for a natural realization in terms of a vertex cluster. It is shown wit...
متن کاملOrthorhombic rational approximants for decagonal quasicrystals
An important exercise in the study of rational approximants is to derive their metric, especially in relation to the corresponding quasicrystal or the underlying clusters. Kuo’s model has been the widely accepted model to calculate the metric of the decagonal approximants. Using an alternate model, the metric of the approximants and other complex structures with the icosahedral cluster are expl...
