The space P3 is introduced, derived from unit-cell axial lengths and interaxial angles. P3 enables linearization of unit-cell parameters using three polar coordinate bases. P3 serves as a compact, interpretable alternative to more abstract ...

Quasicrystals, materials with long-range order but no periodicity, were first discovered in nature within the Khatyrka meteorite, a CV3 carbonaceous chondrite. Their occurrence demonstrated that hypervelocity impacts can generate quasiperio...

Tangles are defined as embeddings of connected graphs that contain knots and/or links as substructures. We enumerate and describe piecewise-linear embeddings of cubic and icosahedral tangles and linked polyhedra with transitivity [1 2]; tha...

This study presents a comprehensive characterization of the symmetry structures of tilings on a Klein bottle, arising from tilings of the Euclidean plane with crystallographic symmetry groups {/cal G} containing a subgroup {/cal L} of type ...

New quasicrystals with rare-earth elements and Li are synthesized with the self-flux method. The starting composition involves 62.8 at.% Zn, 28.6 at.% Mg, 3.6 at. % rare-earth and 5% Li. Alternatively, 66 at.% Zn, 24.8 at.% Mg, 3.9 at.% rar...

Tsai-type 1/1 quasicrystalline approximants in the Au-Si-RE (RE = Ho, Tb) system are body-centered cubic phases decorated by clusters having their inner part occupied by either a disordered tetrahedron (IT) or a single rare-earth atom (CC)....

Quantitative assessment of the structural quality of quasicrystals is a challenging task. Whereas diffraction techniques are a powerful tool for the coherently scattering regions, only diffuse scattering addresses structural inhomogeneities...

A practical approach is proposed to construct short presentations for Euclidean crystallographic groups in terms of generators and relations. For our purposes a short presentation is one with a small number of short relators for a given gen...

Given the integral lattice Λd in d-dimensional Euclidean space, partitions of the lattice nodes into orbits of finite-index subgroups of Aut(Λd) have been computed for d ≤ 4. These partitions can be interpreted as colourings of orbits de...
