Although passive photonic devices have revealed fundamental principles of topological physics, their static configurations limit the investigation of dynamical topological phenomena, phase transitions and disorder effects. However, global controls implemented through nonlinear optical interactions and/or external excitations provide dynamic control of topological properties and precise engineering of non-Hermitian effects for optical routing, fast switching, active lasing and quantum light generation. Programmable photonic circuits offer site-resolved addressing and control of individual photonic atoms, enabling full dynamic manipulation of topological phases, controlled disorder engineering and access to a range of lattice geometries. Together, these approaches are transforming topological photonics from a platform for static demonstration into one for active, reconfigurable control. In this article, we review recent advances in reconfigurable and programmable integrated topological photonics, wherein global and site-resolved control techniques enable reprogrammable manipulation of photonic topological devices with one-dimensional to three-dimensional geometries for fundamental research and practical applications. We discuss future research directions to improve controllability and scalability, including multi-scale control, photon–photon interactions and heterogeneous integration. Topological photonic chips can be controlled globally, across the lattice, and locally, at the level of individual sites. This Review discusses these programmable and reconfigurable technologies for topological, quantum and non-Hermitian physics.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":"8 6","pages":"327-343"},"PeriodicalIF":39.5,"publicationDate":"2026-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148203132","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}

Early approaches often relied on simplified models or empirical parameters, limiting both their accuracy and predictive capabilities. Recent advances in first-principles calculations have enabled rigorous quantification of band structures and scattering processes without empirical parameters, which makes it possible to directly compute electronic transport properties — such as mobility and conductivity — with unprecedented details and even predict novel materials. In this Review, we illustrate material cases in which first-principles approaches have provided detailed and quantitative insights into the electron transport mechanisms and highlight the emergent chemical intuition that rationalizes these transport properties. We discuss how these insights have guided the discovery of new materials, including high-mobility semiconductors and thermoelectric compounds, and the potential to expand these first-principles techniques to a broader class of materials and structures. Recent advances in first-principles computation are enabling quantitative predictions of electronic transport properties in materials. This Review explores the material insights and chemical intuition these advances offer and highlights prospects for discovering new materials across a broader spectrum.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":"8 5","pages":"291-305"},"PeriodicalIF":39.5,"publicationDate":"2026-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147865839","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}

However, a closer look reveals length scales and timescales introduced by quantum dipole fluctuations due to interband mixing, which are reflected in the momentum-space textures of the electronic wavefunctions. This structure is usually referred to as quantum geometry. These new scales not only qualitatively modify the linear and nonlinear responses of a material but can also have a vital role in determining the many-body ground state at low temperatures. In this Perspective, we explore how quantum geometry affects properties of materials and outline recent experimental advances that have begun to explore quantum geometric effects in various condensed matter platforms. We discuss the separation of scales that can allow us to estimate the significance of quantum geometry in various response functions. Quantum geometry captures how electronic wavefunctions delocalize across crystal lattices, introducing length and energy scales beyond band dispersion. This Perspective shows how these hidden scales shape material properties, from dielectric response and optical absorption to the robustness of superconductivity and other emergent phases.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":"8 4","pages":"226-239"},"PeriodicalIF":39.5,"publicationDate":"2026-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147631889","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}
