The quasi-one-dimensional frustrated antiferromagnet CuGeO3 undergoes a spin-Peierls transition to a low-temperature phase of spin singlet dimers. Here we observe an energy-dependent variation of quasiparticle character—from weakly interacting, deconfined spinons at high energy to tightly bound triplons at lower energy. Comparisons between neutron spectroscopy data and tensor network simulations reveal substantial next-nearest-neighbour frustration and weak explicit dimerization from the three-dimensional structure, placing the system in a regime dominated by spontaneous dimerization. The triplon character of the quasiparticles at lower energies persists into the two-particle regime, forming a structured two-triplon continuum with a spectral feature associated with a van Hove singularity at its lower boundary. These findings, whose understanding requires considering both spontaneous and explicit dimerization, demonstrate how the interplay between frustration and dimerization can reshape fractionalization and confinement.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"24 1","pages":""},"PeriodicalIF":19.6,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149010554","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}

Myxococcus xanthus, a bacterial predator, can produce very large multicellular patterns, transitioning from swarming to rippling because of changes in the local environment within and around prey colonies. Here we show that this transition can be explained by two simple properties—local cellular alignment induced by an extracellular matrix and the ability of cells to resolve congestion by reversing. Our high-resolution microscopy and theoretical analysis demonstrate that a tunable refractory period in the reversal control system enables a wide range of collective adaptations, allowing cells to synchronize during rippling and relieve congestion during swarming. Our models suggest that these transitions can occur without genetic regulation changes and result in stable spatial domains that facilitate local differentiation.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"47 1","pages":""},"PeriodicalIF":19.6,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149010555","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}

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}
