Their physics offers difficult challenges because it often occurs far from equilibrium, in materials that lack symmetries and that evolve through complex energy landscapes. We review theoretical efforts from recent years to provide microscopic insights into the mechanical properties of amorphous media using approaches from statistical mechanics as unifying frameworks. Our focus is on how amorphous solids become unstable and yield under applied deformations. We cover both the initial regime, corresponding to small deformations of the solid, and the transition between elastic response and plastic flow when the solid yields. We discuss the specific features arising for systems evolving near a jamming transition and extend our discussion to recent studies of the rheology of dense biological and active materials. We emphasize the importance of a unified approach to studying the response to deformation and the yielding instability of a broad range of disordered media. Amorphous materials yield through complex, history-dependent mechanisms involving localized defects and avalanche dynamics. This Review unifies theoretical advances across glasses, foams, biological tissues and active matter, revealing universal features and critical behaviour that govern the transition from elasticity to plastic flow and macroscopic failure.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":"7 6","pages":"313-330"},"PeriodicalIF":39.5,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123673","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}

For periodic architectures, the design can draw on concepts from solid-state physics, such as crystal symmetries, reciprocal space, band structures and Floquet–Bloch eigenfunctions. Recently, nonlocality has emerged as a design paradigm, enabling both static and dynamic properties that are unattainable with a local design. In principle, all material properties described by linear response functions can be nonlocal, but for ordinary solids, local descriptions are mostly good approximations, leaving nonlocal effects as corrections. However, metamaterials and metasurfaces can be designed to go far beyond local behaviour. This Review covers these anomalous behaviours in elasticity, acoustics, electromagnetism, optics and diffusion. In the dynamic regime, nonlocal interactions enable versatile band structure and refraction engineering. In the static regime, they result in large decay lengths of ‘frozen’ evanescent Bloch modes, leading to strong size effects. For zero modes, the decay length diverges. Nonlocality has gained increasing attention in metamaterial and metasurface design. This Review discusses recent advances, focusing on the physical mechanisms of nonlocality that lead to intriguing properties and functions.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":"7 6","pages":"299-312"},"PeriodicalIF":39.5,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123678","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}

These are elementary particles, which exist in three different flavours and change the latter as they propagate in the dense core of astrophysical sources as well as en route to Earth. To capitalize on existing and upcoming multi-messenger opportunities, it is crucial to understand: (1) the role of neutrinos in explosive transient sources as well as in the synthesis of the elements heavier than iron; (2) the impact of neutrino physics on the multi-messenger observables and (3) the information on the source physics carried by the detectable neutrino signal. In this Review, the status of this exciting and fast-moving field is outlined, focusing on astrophysical sources linked to collapsing massive stars and neutron-star mergers. In the light of the upcoming plethora of multi-messenger data, outstanding open issues concerning the optimization of multi-messenger detection strategies are discussed.

However, producing scalable photonic artificial intelligence (AI) solutions remains challenging. To make photonic AI models viable, the scalability problem needs to be solved. Large optical AI models implemented on PNNs are only commercially feasible if the advantages of optical computation outweigh the cost of their input–output overhead. In this Perspective, we discuss how field-programmable metasurface technology may become a key hardware ingredient in achieving scalable photonic AI accelerators and how it can compete with current digital electronic technologies. Programmability or reconfigurability is a pivotal component for PNN hardware, enabling in situ training and accommodating non-stationary use cases that require fine-tuning or transfer learning. Co-integration with electronics, 3D stacking and large-scale manufacturing of metasurfaces would significantly improve PNN scalability and functionalities. Programmable metasurfaces could address some of the current challenges that PNNs face and enable next-generation photonic AI technology. Programmable metasurfaces may offer a transformative approach to scalable photonic neural networks by overcoming key hardware limitations. This Perspective explores their potential to enhance energy efficiency, computation speed, and adaptability, positioning them as a promising alternative to traditional digital artificial intelligence hardware.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":"7 6","pages":"331-347"},"PeriodicalIF":39.5,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123679","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}

Although the transition from petaflops to exascale computing has been marked by a steady increase in computational power, it is accompanied by a shift towards heterogeneous architectures, with graphical processing units (GPUs) in particular gaining a dominant role. The exascale era therefore demands a fundamental shift in software development strategies. This Perspective examines the changing landscape of hardware and software for exascale computing, highlighting the limitations of traditional algorithms and software implementations in light of the increasing use of heterogeneous architectures in high-end systems. We discuss the challenges of adapting quantum chemistry software to these new architectures, including the fragmentation of the software stack, the need for more efficient algorithms (including reduced precision versions) tailored for GPUs, and the importance of developing standardized libraries and programming models. The exascale era, driven by GPU-dominated architectures, demands a shift in quantum simulation software.
