This paper demonstrates that encapsulating hydrogen-capped polyynes within electrically insulating ultrathin boron nitride nanotubes enables the creation of near-ideal carbyne chains, overcoming previous limitations of endgroup effects and host-guest coupling to reveal intrinsic vibrational and electronic properties for the first time.
This paper presents a systematic, numerically efficient method for computing topological invariants in both crystalline and non-crystalline systems by treating the spectral localizer as an auxiliary zero-dimensional Hamiltonian, thereby reducing complex higher-dimensional topology to simple matrix signatures or Pfaffian signs that can be calculated directly in real space.
The paper predicts a semiclassical nonlinear topological orbital response in antiferromagnetic skyrmions, where spin-dependent emergent Lorentz forces generate electric-field-quadratic orbital currents and accumulations that enable rectified detection distinct from quantum-regime effects.
This paper investigates the tunable topological properties of twisted bilayer-trilayer graphene across four stacking configurations, demonstrating that perpendicular electric fields and twist angles effectively control flat band stability and induce topological transitions with tunable Chern numbers, while Hartree potentials primarily cause weak band reshaping.
By combining multi-modal experimental techniques with theoretical calculations, this study demonstrates that stoichiometric FeTe exhibits nodal or deep-minima superconductivity characterized by power-law temperature dependence and spatial inhomogeneity, establishing it as a distinct regime in the iron-chalcogenide phase diagram that challenges existing microscopic theories.
This paper proposes that multicomponent superconductors with rotational symmetry host -flux bound states exhibiting non-Abelian statistics of parafermions, where their braiding operations can be manipulated and read out via fermionic occupation numbers and crossed-Andreev reflection to realize a complete set of parafermion gates.
This paper introduces a squared-Hamiltonian framework demonstrating that lattice relaxation stabilizes the first magic angle in twisted bilayer graphene by balancing confinement and current-like channels near a special uniform confinement point, while simultaneously destabilizing higher-order magic angles through enhanced remote-band hybridization and localization.
This perspective article reviews two decades of research from the University of Nottingham that explores the full spectrum of tip-sample interactions in atomic force microscopy, emphasizing the probe's active role in phenomena ranging from van der Waals forces to covalent bonding and atom-by-atom assembly, while also addressing challenges in non-invasive diffusion measurements and the emerging application of machine learning in atomic manipulation.
This paper demonstrates that the local density of states induced by non-magnetic impurities in gapped two-band models can serve as a direct spectroscopic probe to extract both the wavefunction winding number and the local Berry curvature, establishing a general connection between these non-local topological properties and observable energy dispersion parameters.
Using qPlus atomic force microscopy and scanning tunneling microscopy on single-crystal Pb(111), this study experimentally demonstrates that electrostatic screening in a type-I superconductor remains governed by the Thomas-Fermi length rather than the London penetration depth, thereby contradicting J. E. Hirsch's alternative theory and confirming that the longitudinal response is unchanged upon entering the superconducting state.
