Simulation of topological phases with color center arrays in phononic crystals
Physical Review Research, 2020 We propose an efficient scheme for simulating the topological phases of matter based on silicon-vacancy (SiV) center arrays in phononic crystals. This phononic band-gap structure allows for long-range spin-spin interactions with a tunable profile.

Self‐Assembly of a Colloidal Honeycomb Crystal in Silico for Topological Valley Photonics
Small, Volume 22, Issue 62, 6 November 2026.The self‐assembly of a colloidal honeycomb crystal is demonstrated in computer simulations, using an assembly strategy that not only suppresses the formation of real‐space topological defects observed experimentally but also yields topological photonic properties in reciprocal space.

Anomalous Sub‐Band Gap Emission at Room Temperature in Mixed‐Dimensional WS2/Cu2O Heterostructures
Small, Volume 22, Issue 62, 6 November 2026.Monolayer WS2 on Cu2O produces a room‐temperature sub‐bandgap emission from the hybrid interface. Spectroscopy and electrical bias measurements indicate that this emission arises primarily from WS2‐modified Cu2O defect states rather than interlayer excitons.

Granular Crystals: Controlling Mechanical Energy with Nonlinearity and Discreteness [PDF]
, 2011 The presence of structural discreteness and periodicity can affect the propagation of phonons, sound, and other mechanical waves. A fundamental property of many of the periodic structures and materials designed for this purpose is the presence of ...

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes
Advanced Functional Materials, Volume 36, Issue 81, 8 October 2026.We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Advanced Functional Materials, Volume 36, Issue 84, 19 October 2026.USe3 is introduced as an actinide van der Waals semiconductor that mirrors the quasi‐one‐dimensional physics of transition‐metal trichalcogenides. Polarization‐resolved Raman spectroscopy on exfoliated flakes maps strong in‐plane phonon anisotropy and strain‐tunable mode shifts.

Experimental study on the sound absorption characteristics of continuously graded phononic crystals
AIP Advances, 2016 Novel three-dimensional (3D) continuously graded phononic crystals (CGPCs) have been designed, and fabricated by 3D printing. Each of the CGPCs is an entity instead of a combination of several other samples, and the porosity distribution of the CGPC ...

The Propagation, Excitation and Coupling of Acoustic Waves in Phonon Band-gap Materials
四川大学学报. 自然科学版, 2005 Acoustic wave exhibits inherently different characters of propagation, excitation and coupling in phonon band-gap materials in which its elastic, piezoelectric constants are modulated in order of acoustic wavelength.

Soda Cans Metamaterial: A Subwavelength-Scaled Phononic Crystal
Crystals, 2016 Photonic or phononic crystals and metamaterials, due to their very different typical spatial scales—wavelength and deep subwavelength—and underlying physical mechanisms—Bragg interferences or local resonances—, are often considered to be very different ...
