We draw examples and experience from astronomy, but the advice is potentially applicable to other areas of science. This Expert Recommendation provides a guide to setting up machine learning projects that are less time-consuming and more likely to lead to robust and useful scientific insights.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":null,"pages":null},"PeriodicalIF":44.8,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141926281","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}

This might appear counter-intuitive as mathematical sciences require rigorous definitions, derivations and proofs, in contrast to the experimental sciences, which rely on the modelling of data with error bars. In this Perspective, we categorize the approaches to mathematical and theoretical discovery as ‘top-down’, ‘bottom-up’ and ‘meta-mathematics’. We review the progress over the past few years, comparing and contrasting both the advances and the shortcomings of each approach. We believe that although the theorist is not in danger of being replaced by AI systems in the near future, the combination of human expertise and AI algorithms will become an integral part of theoretical research. Advances in artificial-intelligence-assisted mathematical investigations suggest that human–machine collaboration will be an integral part of future theoretical research.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":null,"pages":null},"PeriodicalIF":44.8,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141936385","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}

In this Technical Review, we analyse Eliashberg theory, density functional theory for superconductors as well as McMillan and Allen–Dynes equations, providing a summary of the underlying approximations and capabilities. We highlight in simple terms and with examples the many sources of error, which may lead to inaccurate predictions, including limitations on the applicability of the methods, subtle convergence aspects and improper practices often adopted to simplify the treatment of Coulomb interactions. Additionally, we compare the accuracy of the various methods by computing the critical temperature (Tc) for a broad range of superconductors and benchmarking against experimental results. We find that even the simple McMillan and Allen–Dynes formulas give Tc distributions centred on the experimental values. The Eliashberg theory and density functional theory for superconductors yield more peaked distributions, strongly reducing the possibility of incorrect predictions. Ab initio theories of superconductivity allow characterizing and predicting phonon-mediated superconductors. This Technical Review provides an analysis of the different theories, highlighting the main sources of error, either due to inherent approximations or arising from improper practices, and provides a comparison against experimental results.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":null,"pages":null},"PeriodicalIF":44.8,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141866534","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}

Originally considered in the context of the unification of quantum mechanics and general relativity, these causally indefinite processes have been shown to offer advantages in a wide variety of quantum-information processing tasks, ranging from quantum computation to quantum metrology. Here, we overview these advantages and the experimental efforts to realize them. We survey both the experimental techniques employed and the theoretical methods developed in support of the experiments, before discussing the interpretations of current experimental results and giving an outlook on the future of the field. Quantum superpositions of orders of operations can be used to create an indefinite causal order. This Review covers experimental implementations of such processes, focusing on characterization techniques, and discusses their applications and limitations.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":null,"pages":null},"PeriodicalIF":44.8,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141737645","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}

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