Skyrmions in Scalar Fields of Non‐Hermitian Optical Microcavities: Spontaneous Formation, Nonlinear Control, and Optical Forces

Nanophotonics, Volume 15, Issue 19, 13 October 2026.
Skyrmion topology is shown to emerge spontaneously in scalar fields of driven‐dissipative optical microcavities, without externally imposed phase structure. In exciton‐polariton condensates, non‐Hermitian flow generates isolated Skyrmions and self‐organized Skyrmion lattices, while optical nonlinearities enable switching and reconfiguration of their ...

Tensor network approach to momentum-resolved spectroscopy in nonperiodic super-moiré systems

Physical Review Research
Computing spectral functions in large, nonperiodic super-moiré systems remains an open problem due to the exceptionally large system size that must be considered.

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

Azobenzene's Cross‐Scale Optics and Photonics: Molecular Photoswitching, Mesoscopic Material Motions, and Adaptive Devices

Advanced Materials, Volume 38, Issue 56, 8 October 2026.
Azobenzene photoswitches translate molecular‐scale E/Z photoisomerization into macroscopic material responses and device‐level photonic functions. This Review highlights how azobenzene research has evolved from molecular photochemistry to photoalignment, mass migration, photomechanics, and heat release, ultimately enabling holography, reconfigurable ...

CVD Grown Hybrid MoSe2–WSe2 Lateral/Vertical Heterostructures With Strong Interlayer Exciton Emission

Advanced Materials, Volume 38, Issue 57, 13 October 2026.
A scalable bottom‐up CVD methodology, based on liquid transition metal salt precursors, is presented for the controlled growth of two high‐quality MoSe2–WSe2 heterostructures (HSs): purely lateral (HS I) and hybrid lateral/vertical (HS II), by simply adjusting precursor concentration.

Parafermions in moiré minibands

Moiré materials provide a remarkably tunable platform for topological and strongly correlated quantum phases of matter. Very recently, the first Abelian fractional Chern insulators (FCIs) at zero magnetic field have been experimentally demonstrated, and ...

A Moiré Removal Method Based on Peak Filtering and Image Enhancement

Mathematics
Screen photos often suffer from moiré patterns, which significantly affect their visual quality. Although many deep learning-based methods for removing moiré patterns have been proposed, they fail to recover images with complex textures and heavy moiré ...

Tailoring Symmetry Breaking in Engineered van der Waals Superlattices

Advanced Materials, Volume 38, Issue 57, 13 October 2026.
We pioneer a scheme to tailor superpotentials in graphene based on intrinsic substrate electronic orders rather than twist angle. The resulting superpotential folds graphene's Dirac cones to either Γ$\Gamma$ or K‐points, leading to distinct symmetry behaviors.

DNA moiré superlattices

Moiré superlattices have been extensively designed and implemented in atomic-scale van der Waals systems and submicrometre-scale photonic systems. However, bridging the structural gap between these scales has remained a substantial challenge.

Controlled Growth of Boron Nitride in Various Phases

Advanced Materials Interfaces, Volume 13, Issue 19, 6 October 2026.
Phase‐selective boron nitride growth is presented as a unified materials‐design problem across hexagonal, rhombohedral, cubic, and amorphous phases. By linking synthesis routes to thermodynamic stability, kinetic accessibility, surface diffusion, interfacial templating, and energetic activation, this review clarifies how bonding and stacking are ...
