Approximate lattice matching in three dimensions

A solution is proposed for the problem of best matching the lattices of unit cells that are described in different presentations along with the three-dimensional matrix that defines the relationship...

P3, linearizing unit-cell parameters

P3 is a linearized description of unit-cell parameters, created from the usual lengths and angles of the unit cell. It provides a useful metric for comparing unit cells and a convenient base for...

Quasicrystals from the edge: extreme environments, impact craters and the quest in other celestial...

Natural quasicrystals from the Khatyrka meteorite reveal that hypervelocity impacts can generate and preserve quasiperiodic phases under extreme non-equilibrium conditions. Their occurrence highlig...

Minimal-transitivity finite tangles and catenated polyhedra

We enumerate and describe piecewise-linear embeddings of cubic and icosahedral tangles and linked polyhedra with one kind of vertex and two kinds of edge.

Symmetry structures of tilings on a Klein bottle

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...

A new order parameter model for the structural phase transitions in VO2-based solid solutions

To describe the structural phase transitions P42/mnm(R) ↔ P21/c(M1) ↔ P1(T) ↔ C2/m(M2) observed experimentally in VO2 and its solid solutions, the two-component order parameter model is newly...

Geometric indicators of local plasticity in glasses measured by scanning small-beam diffraction

Deformation defects in structurally disordered glasses are much more difficult to detect and characterize than defects in crystals. Here we show how well defined geometric indicators of local...

An extensible Julia toolkit for symmetry-aware dual-space phasing in arbitrary dimensions

A Julia toolkit for dual-space phasing in arbitrary dimensions is presented. It offers a flexible platform for developing and testing charge-flipping algorithms under symmetry constraints.
