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.

Directional Lasing from a 3D Blue Phase Photonic Crystal
Advanced Optical Materials, EarlyView.This work presents the first directional lasing from millimeter‐scale monocrystalline 3D photonic crystals, specifically Blue Phases (BPs), overcoming prior limitations of random lasing in polycrystals. These 3D soft photonic crystals enable highly directional, circularly polarized, mirrorless lasing via resonant polarization modes, offering the ...

Information Transmission Strategies for Self‐Organized Robotic Aggregation
Advanced Robotics Research, EarlyView.In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.
