Advanced Science, EarlyView.By utilizing a hot‐pressing (HP) annealing strategy, Cs3Cu2I5 films with larger grains vertically spanning the entire thickness are fabricated. Because HP annealing enhances light utilization and charge transport in Cs3Cu2I5/GaN heterojunction, the HP device achieves superior detection performance while maintaining narrowband photoresponse to UVA/UVB ...

Topologically Protected Negative Entanglement
Advanced Science, EarlyView.It is revealed that topological flat‐band edge states can lead to robust unconventional negative entanglement entropy scaling. This arises from a new mechanism of non‐Hermitian critical skin compression (nHCSC), which strongly “compresses” quantum information beyond flat‐band degeneracy.

Physical Interpretation of Diffractive Optical Networks for High‐Dimensional Vortex Mode Sorting
Advanced Science, EarlyView.The first layer‐resolved physical interpretation of diffractive optical networks trained for high‐dimensional vortex mode sorting is presented, revealing transformation division phenomena linked to saturated performance as layer numbers increase. This analysis reconciles physical theorems with network operations, enabling physics‐driven design of ...

Delayformer: Spatiotemporal Transformation for Predicting High‐Dimensional Dynamics
Advanced Science, EarlyView.Delayformer introduces a multivariate spatiotemporal transformation (mvSTI) that converts observed variables into delay‐embedded states and cross‐learns their dynamics using a shared Vision Transformer encoder. This approach, grounded in dynamical systems theory, simultaneously predicts all variables in high‐dimensional systems, outperforming state‐of ...
