Numerical studies are often constrained to studying simplified models and lattices. Here we propose a time-dependent correlated ansatz for the dynamical preparation of a quantum-spin-liquid state on a Rydberg atom simulator. Together with a time-dependent variational Monte Carlo technique, we can faithfully represent the state of the system throughout the entire dynamical preparation protocol. We are able to match not only the physically correct form of the Rydberg atom Hamiltonian but also the relevant lattice topology at system sizes that exceed current experimental capabilities. This approach gives access to global quantities such as the topological entanglement entropy, providing insight into the topological properties of the system. Our results confirm the topological properties of the state during the dynamical preparation protocol, and deepen our understanding of topological entanglement dynamics. We show that, while the simulated state exhibits local properties resembling those of a resonating-valence-bond state, in agreement with experimental observations, it lacks the latter’s characteristic topological entanglement entropy signature irrespective of the degree of adiabaticity of the protocol.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"717 1","pages":""},"PeriodicalIF":19.6,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144715338","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}

Central to this process is the formation of molecular clutches, which are dynamic linkages between the extracellular matrix and the actin cytoskeleton mediated by integrins and adaptor proteins. Although it is well known that force-dependent interactions between molecular-clutch components are essential for sensing substrate rigidity, the influence of nonlinear adaptor-protein elasticity is poorly understood. Here we show that adaptor-protein elasticity and local interactions between molecular clutches and the extracellular matrix are key to cellular perception of substrate stiffness. We present a semi-analytical theory that integrates experimentally measured force responses of adaptor proteins to describe cell-adhesion sensing. We propose that molecular clutches probe local mechanical substrate properties and collectively function as a differential that allows a retrograde actin flow and substrate movement to occur at different rates while maintaining a stable mechanical coupling between them. Our model reproduces experimentally measured force-loading rates of individual molecular clutches and correctly predicts cell-adhesion behaviour for a range of substrate stiffnesses. The framework presented can be extended to study complex phenomena such as focal-adhesion maturation and cell-type-specific mechanosensing.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"153 1","pages":""},"PeriodicalIF":19.6,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144652565","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}

A monopolar sound source located at the centre of the structure emitted frequencies between 7,600 Hz and 12,800 Hz (which is within treble audio frequency range) with equal power throughout. Because of reciprocity, the emission and reception properties of such a device are reversible — hence the design as an emitter, which is more feasible to realize experimentally than a receiver.Christiansen and colleagues solved the design task for such an emitter numerically as an iterative process in which they compared the desired target emission pattern to the acoustic pattern produced by the proposed structure. By minimizing a well-defined figure of merit, the team obtained the optimal geometry. Continuous pressure fields were assumed, as well as negligible mechanical vibrations in the device. The result of this formidable computational exercise was a square mask with 28 subwavelength features, which they then fabricated as a 10 cm by 10 cm structure on a substrate (pictured). The researchers demonstrated that this device had the desired spatio-spectral response and a high efficiency over the complete frequency range of the source.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"37 1","pages":""},"PeriodicalIF":19.6,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144629528","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}
