This limitation steered nanophotonics towards plasmonics, in which subwavelength confinement can be achieved at the expense of material absorption. Singular nanophotonics, also called singulonics, is an emerging regime in nanophotonics, which can overcome the trade-off between confinement and loss by leveraging the singular dispersion equation in lossless dielectric media, giving rise to highly localized singular modes, called narwhal wavefunctions. This framework establishes a rigorous, lossless pathway to sub-diffraction confinement, grounded in Maxwell’s equations and governed by the interplay between spatial and momentum uncertainties. This Perspective presents the theoretical foundations and experimental realizations of singular nanophotonics, contrasts it with conventional plasmonic and dielectric approaches and explores its broad implications and challenges. Overcoming the diffraction limit in lossless dielectrics has long been thought impossible. This Perspective explores how the narwhal wavefunction enables lossless, deep-subwavelength optical confinement, offering a new framework for dielectric nanophotonics.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":"8 4","pages":"240-252"},"PeriodicalIF":39.5,"publicationDate":"2026-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147631877","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 decade, the exploration of new structures and optical performance in these systems, supported by advanced nanophotonic characterization techniques, has established upconversion as its own research field. Although these investigations highlight the unique photophysics of the current generation of these materials, it is equally important to recognize their transformative potential in cross-disciplinary applications and their potential relevance in addressing global health threats, such as COVID-19. This Review covers fundamental mechanisms and properties of upconverting nanoparticles, explores their emerging photophysical behaviours and highlights their broad biomedical applications in imaging, 3D printing, sensing, diagnostics and therapeutics. Furthermore, we highlight challenges and opportunities that lie ahead for the upconversion field. Lanthanide-doped upconverting nanoparticles enable nonlinear anti-Stokes light conversion, which has shown unique photophysics and cross-disciplinary, particularly biomedical, applications. This Review covers mechanisms, uses and field-shaping challenges and chances.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":"8 4","pages":"195-207"},"PeriodicalIF":39.5,"publicationDate":"2026-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147631869","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}

Spintronic devices function by electrically manipulating the collective dynamics of the electron spin, which is inherently non-volatile, nonlinear and fast operating, and can couple to other degrees of freedom such as photonic and phononic systems. This Technical Review explores key advances in integrating magnetic and spintronic elements into computational architectures, ranging from fundamental components such as radiofrequency neurons or synapses and spintronic probabilistic bits to broader frameworks such as reservoir computing and magnetic Ising machines. For each of these systems, we discuss hardware-specific and task-dependent metrics to evaluate their computing performance and evaluate the physical processes that need to be optimized to increase performance. Finally, we discuss challenges and future opportunities, highlighting the potential of spin-based computing in next-generation technologies. A number of different platforms for spin-based computing have emerged over the past few years, offering energy-efficient computing methods. This Technical Review identifies key metrics that must be evaluated to benchmark their performance.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":"8 4","pages":"208-225"},"PeriodicalIF":39.5,"publicationDate":"2026-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147631876","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}
