Here we report a photonic platform capturing the symmetry features of altermagnetism. Using a magnetophotonic crystal with staggered magnetic bias and controlled structural variation, we observe momentum-dependent polarization splitting, spin–momentum locking and vanishing net magnetization in the photonic band structure. By solving Maxwell’s equations, we show that the momentum-dependent splitting is symmetry governed, rather than a consequence of the momentum-independent gyrotropic effect. These results demonstrate a photonic analogue of altermagnetic behaviour and provide a route towards spin-functional photonic devices without net magnetization.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"9 1","pages":""},"PeriodicalIF":19.6,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148693458","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}

Recent theories suggested that at low temperature, molecular rearrangements generate elastic stresses that dissipate through the surrounding material and add a non-local contribution to relaxation barriers. However, it is difficult to experimentally measure this elastic contribution. Here we measure the elastic barriers by investigating the transformation of vapour-deposited stable glasses, influenced by distant boundaries of varying elasticity. Rigid boundaries preserve bulk super-Arrhenius dynamics in which both relaxation times and barriers increase on supercooling. By contrast, distant soft boundaries facilitate fast Arrhenius relaxations—even below the glass transition temperature—by allowing faraway stress dissipation. As such, the constant soft-substrate barrier is attributed to local interactions, whereas the differences between barriers on soft and rigid boundaries arise from non-local elastic barriers. Our results show that the rapid dynamical slowdown and vitrification of supercooled liquids are governed by the emergence and growth of elastic barriers, and provide a direct experimental basis for elasticity-based descriptions of the glass transition. Elastic stresses are believed to play a role in the vitrification process in glasses, but measuring them is challenging. Imposing elastic boundary conditions is now shown to provide a way to probe elastic effects within glassy samples.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"22 10","pages":"1633-1638"},"PeriodicalIF":18.0,"publicationDate":"2026-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41567-026-03394-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148693433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
