Line Defects in One-Dimensional Hexagonal Quasicrystals

open access: yesMathematics
Using the eight-dimensional framework of the integral formalism of one-dimensional quasicrystals, the analytical expressions for the displacement fields and stress functions of line defects, which are dislocations and line forces, in one-dimensional ...

Electronic instabilities in Penrose quasicrystals: Competition, coexistence, and collaboration of order

open access: yesPhysical Review Research, 2021
Quasicrystals lack translational symmetry, but can still exhibit long-range order, promoting them to candidates for unconventional physics beyond the paradigm of crystals.

Light wave propagation and diffraction inhibition in three-dimensional photonic quasicrystal lattices

open access: yesResults in Physics, 2023
We have investigated the linear propagation of light wave in three-dimensional photonic quasicrystal lattices by numerical simulation. The diffraction characteristics of the light waves in the longitudinal non-modulated, in-phase modulated and out-of ...

Quantitative analysis of facet growth during directional solidification of salol

open access: yesActa Crystallographica Section B, EarlyView.
This study offers a comprehensive analysis of facet growth during directional solidification of salol, focusing on the dynamic evolution of the solid–liquid interface. A novel strategy was developed to identify the crystallographic nature of the observed facets, whose growth is mainly governed by two‐dimensional nucleation, with deviations attributed ...

Computation and visualization of photonic quasicrystal spectra via Blochs theorem

open access: yes, 2008
Previous methods for determining photonic quasicrystal (PQC) spectra have relied on the use of large supercells to compute the eigenfrequencies and/or local density of states (LDOS).

Three-Dimensional Generalized Dynamics of Soft-Matter Quasicrystals

open access: yesAdvances in Materials Science and Engineering, 2020
The three-dimensional generalized dynamics of soft-matter quasicrystals was investigated, in which the governing equations of the dynamics are derived for observed 12-fold symmetry quasicrystals and possibly observed 8- and 10-fold symmetry ones in soft ...

A maximum density rule for surfaces of quasicrystals [PDF]

open access: yes, 2003
A rule due to Bravais of wide validity for crystals is that their surfaces correspond to the densest planes of atoms in the bulk of the material. Comparing a theoretical model of i-AlPdMn with experimental results, we find that this correspondence breaks

Gapless superconductivity and its real-space topology in quasicrystals

open access: yesPhysical Review Research
We study superconductivity in Ammann-Beenker quasicrystals under magnetic field. By assuming an intrinsic s-wave pairing interaction and solving for mean-field equations self-consistently, we find gapless superconductivity in the quasicrystals at and ...

Forming quasicrystals by monodisperse soft core particles

open access: yesNature Communications, 2017
Quasicrystals with structural symmetries forbidden in crystals have been found in alloys or mono-component systems composed of anisotropic units. Zu et al.

Twists and Turns of Liquid Crystals Unravelled by Small‐Angle Scattering

open access: yesSmall Methods, Volume 10, Issue 3, 9 February 2026.
X‐ray scattering provides valuable insights into material structure and self‐assembly. This review discusses the use of small‐ and wide‐angle X‐ray scattering (SWAXS) as well as grazing incident SWAXS for examining self‐assembled systems, especially liquid crystals.
