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":null,"pages":null},"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}

It can be considered as MoN2 crystal (with a crystal structure of MoS2) intercalating Si2N2 two-dimensional layer (with the structure similar to InSe). The discovery of this material has spurred on research into its electronic properties, and also to the prediction and classification of dozens of other members of the family. Whereas the originally synthesized MoSi2N4 is a semiconductor, some of the members of the family are also metallic, some are magnetic, some showing remarkable properties, such as very high room-temperature electron mobilities. The major interest towards these materials is coming from the septuple-layer structure, which allows not only multiple crystal phases but also complex compositions, in particular those with broken mirror-reflection symmetry against the layer of metal atoms. In this Review, we provide a profile of this new family of materials and discuss the possibilities they open up towards new physics and applications. A new class of septuple-layer 2D materials has been identified, with the first two members already synthesized: MoSi2N4 and WSi2N4. The possible variation of compositions and crystal structures make the new family of 2D materials very versatile and extremely attractive for research and applications.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":null,"pages":null},"PeriodicalIF":44.8,"publicationDate":"2024-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141503552","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}

Liquid metals have proven particularly suited for such studies, partly owing to their small Prandtl numbers that are comparable to those in planetary cores and stellar convection zones, partly owing to their high electrical conductivity that allows the study of various magnetohydrodynamic phenomena. After introducing the theoretical basics and the key dimensionless parameters, we discuss some of the most important liquid-metal experiments on Rayleigh–Bénard convection, Alfvén waves, magnetically triggered flow instabilities such as the magnetorotational and Tayler instability, and the dynamo effect. Finally, we summarize what has been learned so far from those recent experiments and what could be expected from future ones. The understanding of fluid flows and their interaction with magnetic fields in planetary and stellar cores or accretion disks represents a challenge for geophysical and astrophysical research. This Review covers recent liquid-metal experiments on the underlying processes, such as convection, Alfvén waves, the magnetorotational instability and the dynamo effect.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":null,"pages":null},"PeriodicalIF":44.8,"publicationDate":"2024-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141360854","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}
