This paper presents experimental and theoretical evidence for the formation of three-atom-thick gold structures in break-junction systems and introduces a robust method for calibrating atomic-scale distances and assessing electrode sharpness using these structures as a benchmark.
This paper investigates the topological properties of an extended Su-Schrieffer-Heeger model in curved spacetime, demonstrating that while it retains the topological phases of its flat-space counterpart, it exhibits unique spatially asymmetric edge modes and critical slowdown phenomena near transition points that mimic gravitational horizons.
This paper establishes that macroscopic superconducting coherence in hybrid normal-superconducting devices governs deviations from standard thermodynamic uncertainty relations in the subgap regime, leading to the derivation of a generalized quantum uncertainty bound for the Andreev regime that remains universally valid.
This paper investigates finite-size effects in thin films of nodal line semimetals, demonstrating that hybridization of drumhead and bulk surface states can drive transitions into lower-dimensional nodal lines, partially gapped phases with 2D Weyl cones, or fully gapped topological phases characterized by thickness-dependent invariants.
This paper demonstrates that spin-orbit coupled exciton-polariton condensates in a ring configuration can exhibit a controllable dynamical switching of circular polarization via a weakly-nonlinear Josephson junction, offering a promising platform for scalable all-optical spin-switch applications.
This study demonstrates two Hahn echo-based quantum sensing protocols using molecular spins (VO(TPP) and VOPt(SOCPh)₄) embedded in a superconducting resonator to discriminate time-dependent magnetic fields without periodicity matching, achieving sensitivities down to approximately for microsecond-duration signals.
This paper presents a theoretical framework demonstrating that coupled electron-magnon cross-diffusion and spin-angular-momentum transfer in metallic bilayers allow nonequilibrium magnons to suppress unidirectional magnetoresistance, while identifying specific magnetic-field, thickness, and temperature dependencies as experimental fingerprints for distinguishing magnonic contributions.
This study reveals that the finite thickness of quasi-2D Weyl semimetal systems induces a crossover from 2D quantum Hall universality to 3D Gaussian Unitary Ensemble behavior, suggesting that such auxiliary degrees of freedom may explain existing discrepancies in universal critical exponents.
This study experimentally demonstrates that aligning bilayer graphene with hBN induces topological band reconstruction in the resulting moiré superlattice, giving rise to emergent massless, chiral Dirac fermions in secondary bands with significantly reduced Fermi velocity.
This paper proposes a quantum-chemical methodology to establish design rules for helical aromatic foldamers by analyzing - stacking and solvent effects, ultimately identifying a modified compound with enhanced mechanical rigidity and conformational stability for nanoscale electronic applications.
