Time Crystal Platform: From Quasicrystal Structures in Time to Systems with Exotic Interactions. [PDF]

Physical Review Letters, 2017
Time crystals are quantum many-body systems that, due to interactions between particles, are able to spontaneously self-organize their motion in a periodic way in time by analogy with the formation of crystalline structures in space in condensed matter ...

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 ...

From the Fibonacci Icosagrid to E₈ (Part I): The Fibonacci Icosagrid, an H₃ Quasicrystal

Crystals
This paper introduces a new kind of quasicrystal by Fibonacci-spacing a multigrid of a certain symmetry, like H2, H3, T3, etc. Multigrids of a certain symmetry can be used to generate quasicrystals, but multigrid vertices are not a quasicrystal due to ...

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.

ON SELF-SIMILARITIES OF CUT-AND-PROJECT SETS

Acta Polytechnica, 2017
Among the commonly used mathematical models of quasicrystals are Delone sets constructed using a cut-and-project scheme, the so-called cut-and-project sets.

Synthesis of Quasicrystal Al66Cu28Fe15B7 by Melt-Spinning

Orbital: The Electronic Journal of Chemistry, 2021
The melt-spinning process, for printing high cooling rates, is one of the main means for obtaining quasicrystalline alloys. Therefore, in this work this method was used to study the development of the quasicrystalline alloy Al66Cu28Fe15B7. In this sense,

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 ...

First-order localization and quantum phase transition induced by quasicrystal imaginary domain

Physical Review Research
The non-Hermitian extension of quasicrystals provides a highly tunable system for exploring novel material phases. While extended-localized phase transitions have been observed in one dimension, quantum phase transitions in higher dimensions and various ...

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.

Quasicrystal patterns in a neural field model

Physical Review Research, 2020
Doubly periodic patterns in planar neural field models have been extensively studied since the 1970s for their role in explaining geometric visual hallucinations. The study of activity patterns that lack translation invariance has received little, if any,
