Nonetheless, researchers in this field follow rather distinct approaches owing to underappreciated general principles underlying speckle phenomena. For example, speckle can be produced from a simple scatterer or from more complex, multiple scattering geometries. In this Expert Recommendation, we propose a standardization of metrics to quantify intrinsic speckle sensitivity that enables direct comparison between all scattering geometries. Moreover, we provide a general criterion that allows one to predict where multiple scattering is truly advantageous for a given task. This standardization and criterion will catalyse progress in speckle metrology but will also translate to other domains of disordered optics which are undergoing rapid developments at present. Speckle can be harnessed for a wide variety of metrology applications. This Expert Recommendation proposes a standardized metric to allow comparisons of the intrinsic sensitivity of different approaches, and it clarifies when multiple scattering can be beneficial in increasing sensitivity of measurements.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":"6 8","pages":"500-508"},"PeriodicalIF":44.8,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141737646","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}

The COVID-19 pandemic and the proliferation of misinformation are examples that highlight the importance of these dynamic processes. In recent years, it has become clear that studies of higher-order networks may unlock new avenues for investigating such processes. Despite being in its early stages, the examination of social contagion in higher-order networks has witnessed a surge of research and concepts, revealing different functional forms for the spreading dynamics and offering novel insights. This Review presents a focused overview of this body of literature and proposes a unified formalism that covers most of these forms. The goal is to underscore the similarities and distinctions among various models to motivate further research on the general and universal properties of such models. We also highlight that although the path for additional theoretical exploration appears clear, the empirical validation of these models through data or experiments remains scant, with an unsettled roadmap as of today. We therefore conclude with some perspectives aimed at providing possible research directions that could contribute to a better understanding of this class of dynamical processes, both from a theoretical and a data-oriented point of view. Contagion dynamics in higher-order networks have witnessed a surge of research and concepts, offering new insights but also exposing many diverse functional forms of spread. This Review provides a focused overview and proposes a unified formalism covering most of these forms.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":"6 8","pages":"468-482"},"PeriodicalIF":44.8,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141546386","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}
