Designing a minimal Landau model to stabilize desired quasicrystals
Physical Review ResearchInterparticle interactions with multiple length scales play a pivotal role in the formation and stability of quasicrystals. Choosing a minimal set of length scales to stabilize a given quasicrystal is a challenging problem.

Metallic-mean quasicrystals as aperiodic approximants of periodic crystals
Nature Communications, 2019 Quasicrystals differ from traditional incommensurate structures because they have non-crystallographic rotational symmetries. Here the authors introduce a scheme to produce metallic-mean quasicrystals in two dimensions with 6-fold rotational symmetry ...

Quantum Many-Body Topology of Quasicrystals
Physical Review X, 2021 In this paper, we characterize quasicrystalline interacting topological phases of matter, i.e., phases protected by some quasicrystalline structure. We show that the elasticity theory of quasicrystals, which accounts for both “phonon” and “phason” modes,

Growing Perfect Decagonal Quasicrystals by Local Rules
, 2007 A local growth algorithm for a decagonal quasicrystal is presented. We show that a perfect Penrose tiling (PPT) layer can be grown on a decapod tiling layer by a three dimensional (3D) local rule growth. Once a PPT layer begins to form on the upper layer,

Bloch–Landau–Zener Oscillations in Moiré Lattices
Fortschritte der Physik, Volume 73, Issue 11, November 2025.Abstract A theory of two‐dimensional Bloch–Landau–Zener (BLZ) oscillations of wavepackets in incommensurate moiré lattices under the influence of a weak linear gradient is developed. Unlike periodic systems, aperiodic lattices lack translational symmetry and therefore do not exhibit a conventional band‐gap structure.

Identifying and Indexing Icosahedral Quasicrystals from Powder Diffraction Patterns
, 2001 We present a scheme to identify quasicrystals based on powder diffraction data and to provide a standardized indexing. We apply our scheme to a large catalog of powder diffraction patterns, including natural minerals, to look for new quasicrystals. Based

European Journal of Inorganic Chemistry, Volume 28, Issue 26, September 24, 2025.The mixing of the elements indium and thallium is investigated for the Na4A6Tl13 structure type (A = Rb, Cs). Providing of indium instantly results in the formation of [In@Tr12]10– (Tr = In, Tl) cluster units. The dissolution behavior in liquid ammonia was investigated as well as DFT calculations are carried out to elucidate the bonding situation ...
