Mirror Symmetry. The Mother of all Crystal Symmetries


Accepted 26 September 2026

On the symmetry properties and crystallographic generation of the Schwarz minimal P surface

The triply periodic Schwarz minimal P surface is derived from close packing of polyhedra in 3D space, through iterative minimization of the area of the interface that separates the two identical 3D labyrinths that are created in this way.

Maximal independence and regularity of Al/Si distributions in disordered phyllosilicates 2:1

The distribution of aluminium cations in disordered phyllosilicates is analysed according to the concepts of maximal independence and regularity.

Determination of the one-electron reduced Wigner function for a molecular crystal

The first reconstruction of an experimental one-particle reduced Wigner function for electrons in molecular crystals is reported. It relies on an ensemble N-representable model jointly refined from the X-ray diffraction and Compton scattering data.

Predominantly pentagonal ice bilayers: energetics and self-assembly properties

The stability factors of ice bilayers with different arrangements of hydrogen atoms in hydrogen bonds are established. A topological condition for the assembly of bilayers from individual fragments is proposed. Methods for producing bilayers and the main challenges are described.

On the diffraction spectrum of two-dimensional random substitutions

We investigate the spectral properties of two distinct classes of two-dimensional random substitutions: a family of constant-shape block random substitutions and the random Fibonacci direct product variation, which is a nonconstant-shape but geometrically compatible random inflation rule.
