Applications of QSPR and Machine Learning in Molecular Photonics

Advanced Optical Materials, EarlyView.
Quantitative structureproperty relationships (QSPR) and machine learning (ML) are transforming photochemistry by enabling pre‐synthetic screening of photoactive molecules. This review outlines advances in data‐driven discovery of optical materials and functional dyes, identifies effective descriptors and models for photophysical processes, and provides

Illuminating Quantum Phenomena in 2D Materials: The Power of Optical Spectroscopy

Advanced Optical Materials, EarlyView.
Atomically thin 2D materials host quantum tunnelling, plasmonic and excitonic phenomena driven by reduced dimensionality and strong many‐body interactions. This review links these effects to state‐of‐the‐art optical probes—NSOM, pump–probe, CARS, TRR, and optical frequency comb spectroscopy—highlighting how their ultrahigh spatial–temporal resolution ...

Smart Theremin Based on Electromagnetic Metasurfaces for Fine Dual‐Hand Perception

Advanced Optical Materials, EarlyView.
The proposed Meta‐Theremin leverages a frequency‐spatial multiplexing metasurface to enable robust dual‐hand perception by shielding environmental noise and confining EM fields to interaction zones. Its physics‐informed neural network decouples hand‐specific echoes, enhancing accuracy.

Interactions of Nitrogen‐Vacancy Centers in Diamond with Electron Beams: Implications for Quantum Sensing and Photoluminescence Stability

Advanced Optical Materials, EarlyView.
Under the influence of an electron beam, the photoluminescence (PL) and quantum sensing stability of nitrogen‐vacancy (NV) centers in fluorescent nanodiamonds (FNDs) change. This work elucidates structural and functional changes induced by the electron beam in FNDs and identifies imaging conditions to preserve NV properties and offers a pathway for top‐

Record Negative Photoconductivity in N‐Polar AlGaN/GaN Quantum‐Well Heterostructures

Advanced Photonics Research, EarlyView.
The negative photoconductivity (NPC) effect is experimentally observed in the N‐polar AlGaN/GaN quantum‐well heterostructures after introduction of a GaN/AlN superlattice back barrier. The NPC phenomenon appears in the N‐polar AlGaN/GaN quantum‐well heterostructures under infrared light illumination at room temperature.

Methodology for Topological Interface Engineering in 2D Photonic Crystals

Advanced Photonics Research, EarlyView.
This article introduces an automated framework for topological photonic crystal design. It features an iterative band connection method for identifying band crossings, a data‐driven approach for band symmetry recognition, and analysis of how topological mode dispersion trades off with photonic band‐gap size.
