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

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 ...

Fixed Point Theorem for Monotone Non-Expansive Mappings

International Journal of Analysis and Applications, 2021
In this paper, we study the fixed point theorem for monotone nonexpansive mappings in the setting of a uniformly smooth and uniformly convex smooth Banach space.

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 ...

Krasnosel'skii fixed point theorem for dissipative operators

Electronic Journal of Differential Equations, 2011
In this note, a sufficient condition guaranteing the existence of fixed points in a nonempty, closed convex K for T+S is given, where $T:Ksubset Eo E$ is dissipative and $S:Ko E$ is condensing.

A Clarification on Quantum‐Metric‐Induced Nonlinear Transport

Advanced 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
