Engineering Topological Phases with a Traveling‐Wave Spacetime Modulation
Time‐varying systems have garnered considerable attention due to their unique potential in manipulating electromagnetic waves. Here, a novel class of topological spacetime crystals with a traveling‐wave modulation is introduced. By manipulating material anisotropy, one can engineer light angular momentum and non‐trivial topological phases characterized

Reinforcement Learning Enabled Nanophotonic Devices
A reinforcement learning algorithm is used to design photonic devices. The method creates metagratings and grating couplers that efficiently control both the direction and polarization of light. Further, a reinforcement learning approach is used to design in‐plane integrated photonic devices. This approach paves the way for advanced photonic components

Phase‐Retrieved High‐Throughput Multi‐Channel Simultaneous Surface Plasmon Resonance Detection
This work presents a new phase‐retrieval high‐throughput multi‐channel simultaneous SPR detection framework. By integrating an objective lens‐based coupling system with a rotation‐based ePIE (r‐ePIE) phase retrieval on the back focal planes, this framework significantly reduces the minimum required detection area to reveal localized information.

Faraday–Ramsey Rotation in Ultrathin Alkali Vapor Cells as an Analogy to Atomic‐Beam Systems
This work demonstrates that ultrathin rubidium vapor cells can emulate atomic‐beam behavior through geometry‐dependent velocity filtering. Employing a spatially separated pump–probe scheme and Faraday–Ramsey rotation, the study reveals coherent atomic dynamics without buffer gas or anti‐relaxation coatings. This approach offers a compact pathway toward
