Hot‐Pressing Annealing‐Induced Light Utilization Enhancement and Crystallinity Optimization Enable High‐Performance Narrowband Ultraviolet Photodetectors for Real‐Time Ultraviolet Radiation Monitors

open access: yesAdvanced 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

open access: yesAdvanced 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

open access: yesAdvanced 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 ...

A Clarification on Quantum‐Metric‐Induced Nonlinear Transport

open access: yesAdvanced Science, EarlyView.
How does the quantum metric truly govern the nonlinear transport? The longstanding theoretical discrepancies are resolved in quantum‐metric‐induced nonlinear transport and the correct intrinsic nonlinear conductivity is identified. Furthermore, a toy model is engineered to suppress the competing effects, uniquely highlighting the role of quantum metric

Optically Driven Formation of Tailored Phonon Cavities

open access: yesAdvanced Science, EarlyView.
It is demonstrated that a structured optical field creates nanoscale “phonon cavities” in van der Waals materials, where atomic vibrations are confined and controlled in space and time. This approach enables programmable control of cavity geometry, symmetry, and frequency, and provides a platform for ultrafast studies of nonequilibrium interactions and
