This paper introduces DeepConf, a machine learning framework that leverages accelerated Density Functional Theory to generate training data and reconstruct the three-dimensional structures of biomolecules like peptides and glycans from Scanning Tunneling Microscopy images with high accuracy.
This paper demonstrates that light scattering from pairs of point-like dipoles exhibits exact resonances when the dipoles violate the optical theorem (indicating nonequilibrium or active conditions), leading to potentially infinite scattering amplitudes, while similar but finite resonances in equilibrium systems can still yield significant amplification factors.
This paper investigates band modulations and topological transitions in a one-dimensional periodic bead-on-string chain by combining exact transfer-matrix analysis, numerical simulations, and tabletop experiments to demonstrate that localized midgap states are topological solitons governed by the Su-Schrieffer-Heeger model and Dirac theory.
This study utilizes a custom-built cryogenic magneto-THz scattering-type scanning near-field optical microscopy platform to visualize the nanoscale evolution of colossal magnetoresistance in , revealing that magnetic-field-induced spin switching initiates as 1–2 nm isolated sites that coalesce into ~15 nm conducting regions during the transition from an antiferromagnetic insulator to a ferromagnetic metal.
This paper demonstrates that the quantum metric serves as a sensitive geometric probe for persistent spin helices by revealing a divergence caused by a hidden line degeneracy at the balanced spin-orbit coupling condition, which is subsequently regularized by higher-order cubic interactions.
This paper introduces and experimentally validates a novel all-in-plane image sensor architecture that eliminates the need for individual pixel readout circuits by using neighbor-connected photoresistive pixels and reconstructing images via electrical impedance tomography, thereby enabling unprecedented simplification for ultra-miniaturized and heterogeneously integrated detectors.
This review surveys theoretical and experimental advances in the physics of trions within two-dimensional monolayers, highlighting their enhanced binding energies due to reduced screening and confinement, the impact of environmental and external field factors, and their connections to broader many-body phenomena.
This paper presents a microscopic theory demonstrating that bending-induced inhomogeneous spin textures on curved magnetic surfaces can generate a Dzyaloshinskii-Moriya-type interaction between magnetic impurities mediated by itinerant electrons, even in the absence of spin-orbit coupling.
This paper experimentally demonstrates and theoretically models nonlinear mode coupling in high-stress silicon nitride membrane resonators, revealing how tension-mediated geometric nonlinearity and mode symmetry govern intermodal interactions to enable controllable multimode frequency tuning.
Using scanning tunneling microscopy, researchers discovered that YbB exhibits coexisting conducting and insulating surface domains with distinct atomic terminations and band-bending, where the insulating regions disprove its status as a strong topological insulator while the spin-polarized conducting regions suggest potential for spintronic applications.
