A maximum density rule for surfaces of quasicrystals [PDF]

, 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

Time‐Domain Near‐Field Scanning Microscopy of Terahertz Metasurfaces

Advanced Photonics Research, Volume 7, Issue 1, January 2026.
Time‐domain near‐field scanning terahertz microscopy provides direct access to subwavelength electromagnetic fields on metasurfaces. By combining controlled polarization excitation with nanoscale probing, this technique enables quantitative visualization of localized hotspots, surface‐wave propagation, and wavefront manipulation, offering a powerful ...

Three-Dimensional Generalized Dynamics of Soft-Matter Quasicrystals

Advances 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 ...

Computation and visualization of photonic quasicrystal spectra via Blochs theorem

, 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).

Reconstructing Focal Topological Curves through Vortex Spots from Multifocal Metasurfaces

Advanced Science, Volume 12, Issue 48, December 29, 2025.
Multichannel multifocal silicon metasurfaces are built to reconstruct focal topological curves using an array of vortex spots, and upconverted fluorescence is used to directly visualize the morphology of the near‐infrared focal fields. Abstract Structured light plays an important role in modern photonics.

Gapless superconductivity and its real-space topology in quasicrystals

Physical 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 ...

The eight-fold way for optical quasicrystals

, 2013
In a recent Letter we proposed a means to realize a quasicrystal with eight-fold symmetry by trapping particles in an optical potential created by four lasers.

Topological Quasiparticles of Light: From Spin‐Orbit Coupling to Photonic Skyrmions

Laser &Photonics Reviews, Volume 19, Issue 24, December 17, 2025.
This review summarizes recent advances in photonic skyrmions, emphasizing the central role of spin–orbit coupling in their formation. The review discusses how spin–orbit interactions generate skyrmionic textures, examines modulation strategies for their dynamic control, and provides an overview of emerging directions and opportunities where these ...
