Issues related to its description, including the modelling of natural ice dynamics from the smallest to the largest scales, are of great importance. In the natural environment, melting or freezing processes are typically coupled to those of fluid flows. Therefore, the interplay between fluid mechanics and phase-change thermodynamics is a highly topical problem. In recent years, fluid–ice interface problems have been studied via not only field measurements but also laboratory experiments, numerical simulations and theoretical analyses. This Perspective considers the state-of-the-art knowledge of the phenomenology of fluid–ice coupling processes in standardized configurations. These include freezing and melting in thermally stratified natural convection of fresh water, double-diffusive convection and convection in the mushy ice of salty water in confined systems, as well as imposed flows moving along an ice layer or surrounding dispersed ice bodies. It also highlights open questions of geophysical interest that could benefit from fundamental studies with a physical and fluid dynamic approach. The dynamics of water freezing and ice melting in natural environments involves many intricate fluid mechanics processes. To tackle these complexities, examining them in well-controlled laboratory settings proves highly advantageous.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":null,"pages":null},"PeriodicalIF":44.8,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142579819","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}

One of the most fascinating opportunities that ultrashort pulses offer is the possibility of modulating and investigating symmetries by tailoring the properties of the laser beam in the spatial and polarization domains, effectively controlling symmetry breaking on multiple levels. In particular, this allows the probing of chiral matter and ultrafast chiral dynamics. In recent years, the development of highly sensitive approaches for studying chirality has been a hot topic in physics and chemistry that has developed largely separately from the field of tailored light. This Perspective discusses the individual and joint evolution of these fields, with an emphasis on how the fields have already cross-fertilized, opening new opportunities in science. We outline a future outlook of how the topics are expected to fully merge and mutually evolve, emphasizing open issues. This Perspective explores the potential of using tailored fields to investigate chiral matter and ultrafast chiral dynamics. Light fields with well-defined symmetry properties can open new opportunities for research in chiral light–matter interactions.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":null,"pages":null},"PeriodicalIF":44.8,"publicationDate":"2024-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142579813","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}

Over the past few years, Rydberg atoms have been used as sensitive probes for performing self-calibrated and SI-traceable electric field measurements. In this Technical Review, we introduce and examine the current state of Rydberg atom-based electrometry in room-temperature atomic vapours. We cover the fundamental principles, experimental techniques, recent advancements, and applications of this field, providing a comprehensive resource for researchers interested in utilizing Rydberg atoms for precise electric field measurements. Rydberg atoms are sensitive to radio frequency electric fields, which make them useful as sensors. This Technical Review discusses Rydberg sensors that measure the amplitude and phase of electric fields at frequencies from d.c. to THz, as well as technological applications of these sensors.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":null,"pages":null},"PeriodicalIF":44.8,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257111","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}

By avoiding ensemble averaging, single-molecule techniques can resolve structural distributions and fluctuations even for complex and conformationally heterogeneous systems; they also reveal the close link between biological function and the statistical mechanics of the underlying processes. The combination of single-molecule fluorescence detection with Förster resonance energy transfer has become an essential tool for probing biomolecular dynamics on timescales ranging from nanoseconds to days. This Review briefly outlines the state of the art of single-molecule Förster resonance energy transfer spectroscopy and then highlights some of the most important physics-based developments that are expected to further expand the scope of the technique. Key areas of progress include improved time resolution, access to nonequilibrium dynamics and synergies with advances in data analysis and simulations. These developments create new opportunities for attaining a comprehensive understanding of the dynamics and functional mechanisms of biological processes at the nanoscale.
