Muonium, the bound state of a positively charged anti-muon and an electron, offers the possibility to probe gravity in the absence of the strong interaction with second-generation standard model particles. However, the short muon lifetime and the existing diffuse thermal muonium sources rendered such measurements unfeasible. Here we report the generation of a high-brightness muonium beam, which we extract from a thin layer of superfluid helium. The mean longitudinal velocity and narrow spread of the velocity distribution indicate a superthermal beam, and yields are similar to the highest-intensity diffuse sources. This beam is expected to enable muonium interferometry and a per-cent-level measurement of its gravitational acceleration. In addition, its unprecedented brightness opens the way to sub-kilohertz 1S–2S spectroscopy, enabling the precise determination of the muon mass and stringent tests of bound-state quantum electrodynamics.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"3 1","pages":""},"PeriodicalIF":19.6,"publicationDate":"2026-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149010556","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}

Charge transfer is often attributed to ion transfer at the receding contact line. However, it remains an open question whether ion transfer alone can fully account for the observed charge separation. Here we examined slide electrification of polar, self-ionizing liquids and non-polar liquids. By cooling them below the melting temperature, we were able to compare this process to tribocharging of the respective frozen components. Despite reduced ion mobility at sub-freezing temperatures, the frozen polar compounds continued to accumulate substantial charge. Non-polar liquids exhibited lower charging and nearly identical charging behaviour in both their liquid and frozen phases on different substrates. As non-polar liquids contain few free ions, these observations indicate an alternative charging mechanism, which could be electron transfer. Our findings suggest that slide electrification operates through at least two mechanisms, with the dominant charge transfer pathway shifting between ions and electron transfer depending on electronegativity, phase and temperature.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"1 1","pages":""},"PeriodicalIF":19.6,"publicationDate":"2026-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149010557","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}

The restrictions imposed by conformal symmetry give rise to a number of important theoretical techniques that have made these theories central to the understanding of critical phenomena. However, efforts to classify conformal field theories have run into the challenge of identifying lattice models that have a corresponding critical point. Here we introduce an algorithm that we call a conformal field theory factory for methodically generating two-dimensional lattice models that would flow to conformal field theories in the infrared limit. We realize these lattice models by engineering the boundary conditions of three-dimensional topological orders described by string-net models. The critical points are induced by a commensurate condensation of non-commuting anyons. Our structured method generates an infinite family of critical lattice models, including previously unknown critical points. We recover known conformal field theories that preserve the Haagerup symmetries and identify three further candidate theories. The critical couplings of our models are precisely encoded in algebraic data associated with the string-net models, thereby establishing a scheme for discovering and potentially classifying conformal field theories. Conformal field theories have a central role in statistical and high-energy theoretical physics. An algorithm to systematically generate critical lattice models described by different conformal field theories has now been identified.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"22 10","pages":"1699-1706"},"PeriodicalIF":18.0,"publicationDate":"2026-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149010558","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}

Doping an exciton fluid with additional electrons or holes further creates an equilibrium fluid of trions—bound states of two electrons and one hole and vice versa. Therefore, a trion Hall effect under a magnetic field is expected but has not been demonstrated. Here we report the observation of the trion Hall effect in MoSe 2 /WSe 2 heterostructures, which support Coulomb-coupled layers of electrons and holes with continuously tunable densities. The effect arises from the Lorentz force on trions subjected to a perpendicular magnetic field. By combining magnetotransport and Coulomb drag measurements, we find that an electron-like Hall effect emerges on the hole layer in the presence of negatively charged trions because of Coulomb drag. Furthermore, the effect disappears when trions dissociate at elevated temperatures or high doping densities. These results suggest that transition metal dichalcogenide heterostructures are a candidate for realizing trion-based quantum Hall phenomena.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"49 1","pages":""},"PeriodicalIF":19.6,"publicationDate":"2026-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148923413","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}
