This paper characterizes topology in the Su-Schrieffer-Heeger chain at nonzero temperature by comparing three complementary diagnostics for mixed Gaussian states: the ensemble geometric phase, local twist operators, and a generalized local chiral marker, ultimately proposing practical local indicators that remain robust in the thermodynamic limit.
This theoretical study reveals that phonon-induced effects on the absorption spectra of moiré excitons in twisted transition metal dichalcogenide bilayers transition from non-Markovian dynamics and phonon sidebands at small twist angles to Markovian broadening at larger angles, while intraband scattering significantly suppresses higher-energy absorption bands when their bandwidth exceeds the optical phonon energy.
This paper theoretically demonstrates that spatially varying oscillating magnetic fields induce eddy currents in non-magnetic conducting particles, generating steady forces and torques that drive magnetophoresis and amplify concentration fluctuations through anisotropic diffusion.
This paper presents a high-temperature, high-speed atomic force microscopy system utilizing a qPlus sensor, a specialized Quadpod scanner, and hybrid-loop frequency demodulation to achieve atomic-resolution imaging of molten metal/solid interfaces above 200°C, revealing distinct surface structures compared to room-temperature samples.
This paper introduces a vision-transformer-based neural network trained on simulated charge stability diagrams that accurately predicts effective spin-orbit coupling strengths and other Hubbard model parameters in disordered hole spin qubit arrays, offering a powerful tool for their automated characterization.
This paper derives closed-form analytical expressions for the surface response functions and plasmon dispersions of coated multi-layered anisotropic semi-Dirac heterostructures, revealing distinct in-phase and out-of-phase plasmon branches and anisotropic loss behaviors with potential applications in durable protective coatings.
This study demonstrates that controlled topological dilution via random decimation in artificial square spin ice systematically increases frustration and configurational entropy, driving a transition from long-range order to a cooperative glassy magnetic state characterized by aging, dynamical heterogeneity, and Vogel-Fulcher-type freezing.
This paper demonstrates that surface plasmons supported by two-dimensional interfaces with electric and chiral conductivities enable significantly more efficient enantiomer discrimination than chiral optical cavities, achieving nearly an order-of-magnitude improvement through stronger field confinement and a geometric advantage that couples to dipole projections across an entire plane.
This paper demonstrates that in van der Waals materials, particularly multilayer rhombohedral graphene, band geometry and Berry phase effects can induce chiral excitonic bound states and spontaneous symmetry breaking, leading to a unique pairing mechanism where the favored angular momentum channel evolves with flux and mixes multiple states upon the breaking of rotational symmetry.
This paper demonstrates that the edge sideband occupations of non-interacting fermions under monochromatic phase drive are universally governed by the discrete Bessel kernel, which converges to the Airy kernel of random matrix theory at large amplitudes, thereby establishing a direct link between Floquet scattering and universal transport signatures like photo-assisted shot noise.
