This study employs all-atom molecular dynamics simulations using hybrid CHARMM36/ClayFF force fields to systematically investigate how Zn3Al-LDH nanosheets modify Escherichia coli-mimetic membranes. Our results reveal a three-stage interaction process that induces structural reorganization and compaction of the lipid bilayer, manifesting as membrane thickening and a reduced area per lipid. We find that these changes arise from synergistic charge screening and molecular ordering, particularly when the nanosheets are aligned parallel to the membrane. Based on these findings, we propose a dual antimicrobial mechanism that combines mechanical membrane stiffening with oxidative stress induced by Zn2+ leaching. These insights provide a foundation for engineering LDH-based surfaces with enhanced antibacterial efficacy.","PeriodicalId":8094,"journal":{"name":"Applied Physics Letters","volume":"97 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144747110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

We consider several scenarios where small-scale curvature perturbations are naturally enhanced due to the presence of additional spectator fields during inflation. The same spectator fields can lead to a period of early matter domination (EMD) after inflation. We compute the inflationary spectrum of curvature perturbation and determine its evolution at later times, taking into account both the onset and the end of the EMD epoch, and also the impact of relative velocity perturbation between matter and radiation. The feature that the same field is responsible for both enhanced perturbations and the EMD era, leads to a predictive framework within which the full frequency dependence of SGWB can be computed. The SGWB can be observed in several detectors, including those focused on the nano-Hz regime. Our numerical framework can also be used to study other non-standard cosmological histories.","PeriodicalId":15445,"journal":{"name":"Journal of Cosmology and Astroparticle Physics","volume":"7 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144747258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Recently, the existence of embezzling states of bipartite systems of type III von Neumann algebras was shown. However, both the multipartite case and the precise relation between embezzling states and the notion of embezzling families, as originally defined by van Dam and Hayden, was left open. Here, we show that finite-dimensional approximations of multipartite embezzling states form multipartite embezzling families. In contrast, not every embezzling family converges to an embezzling state. We identify an additional consistency condition that ensures that an embezzling family converges to an embezzling state. This criterion distinguishes the embezzling family of van Dam and Hayden from the one by Leung, Toner, and Watrous. The latter generalizes to the multipartite setting. By taking a limit, we obtain a multipartite system of commuting type III$_1$ factors on which every state is an embezzling state. We discuss our results in the context of quantum field theory and quantum many-body physics. As open problems, we ask whether vacua of relativistic quantum fields in more than two spacetime dimensions are multipartite embezzling states and whether multipartite embezzlement allows for an operator-algebraic characterization.","PeriodicalId":20807,"journal":{"name":"Quantum","volume":"26 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144747652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Within the framework of the VBI, a novel signal model is constructed by exploiting the inherent temporal correlation of the incident acoustic signal. In addition, by combining the linear interpolation method, a new off-grid model is constructed. This model improves the accuracy and stability of DOA estimation in the off-grid scenario.

In this context, indoor photovoltaics (IPVs) emerge as a promising technology to enable continuous electricity supply for autonomous IoT systems. To maximize energy harvesting efficiency under indoor conditions, IPV absorbers require an optimal bandgap of 1.7–1.9 eV to match the spectral characteristics of indoor environments as well as high defect tolerance to minimize the defect-induced recombination. These requirements position all-inorganic perovskites (AIPs), particularly CsPbI3 and CsPbI2Br, as superior candidates for IPVs compared to conventional silicon absorbers. This review summarizes recent advancements on AIP-based IPVs, which lead to indoor efficiency exceeding 40%, far surpassing conventional silicon cells. This review also examines a series of synergistic efforts toward the AIP-based IPVs with high performance, further discusses the existing challenges and provides multiple perspectives regarding the future optimization of AIP-based IPVs for practical applications.","PeriodicalId":8094,"journal":{"name":"Applied Physics Letters","volume":"13 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144747107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
