However, achieving customized control over wave transport and localization in disordered systems remains a significant challenge. Notably, wave transport in the weak scattering regime typically exhibits energy‐dilute diffusion, while in the strong scattering regime, Anderson localization is inherently stochastic and unpredictable in location. Here we report an anomalous phase termed staggered‐disorder induced localization (SDIL) in disordered structure, which achieves robust and deterministic localization in disordered systems. Specifically, the SDIL halts wave expansion along a predefined direction while facilitating orthogonal transport within a 2D structure. The SDIL is found persisting across a wide range of disorder strengths for a finite 2D structure. Remarkably, the transport trajectory is fully configurable by engineering the staggered disorder, providing an attractive mechanism for wave routing in disordered systems. Our quasi‐normal mode analysis reveals a localized phase region, wherein emergent high‐quality modes drive this robust localized scattering. These findings establish SDIL as a missing paradigm in scattering physics, providing a universal framework for achieving deterministic wave localization and routing within disordered systems.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"33 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their operational stability and luminescence brightness remain core bottlenecks restricting their commercialization. To address this issue, this study reports an interference crystallization strategy that regulates crystal facet growth to reshape facet competition. By incorporating L‐theanine (LT) into the precursor solution of FAPbBr <jats:sub>3</jats:sub> , the functional groups in LT selectively adsorb onto the (100) crystal facets of the perovskite, thereby suppressing the rapid growth of these facets and significantly enhancing the ordering of the crystal arrangement and crystal quality. Subsequently, 2,4,6‐Tris[3‐(diphenylphosphinyl)phenyl]‐1,3,5‐triazine (POT2T) is further introduced to modify the perovskite interface, synergistically passivating interface defects and confining the carrier recombination zone, thereby effectively suppressing interfacial non‐radiative recombination. Consequently, the fabricated green PeLEDs achieve an external quantum efficiency (EQE) of 23.06% and an ultrahigh luminance of 358 135 cd m <jats:sup>−2</jats:sup> , delivering an outstanding T <jats:sub>50</jats:sub> operational lifetime of 14 923 h at an initial luminance of 100 cd m <jats:sup>−2</jats:sup> .

In this paper, we propose a scheme to manipulate quantum entanglement in molecular COM system coupled with a degenerate optical parametric amplifier (DOPA) under Markovian approximation. We reveal that both strength and phase of DOPA can be tuned to enhance optical‐vibration entanglement and suppress vibration‐vibration entanglement. The optical‐vibration entanglement can exist at room temperature, demonstrating strong robustness against thermal noise. Moreover, we extend results from Markovian to non‐Markovian regimes, which can further enhance both types of entanglement with DOPA fixed. In particular, we find that non‐Markovian effects can reverse influences of DOPA on vibration‐vibration entanglement from suppression to enhancement, leading to regeneration of entanglement. The scheme provides an effective way to control and enhance quantum entanglement in a molecular COM system through steering DOPA and non‐Markovian effects.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"158 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
