This study successfully disentangles the small topological Hall effect from the dominant anomalous Hall effect in Ta/CoFeB/MgO thin films by combining magneto-optical Kerr microscopy with thermal and electrical transport measurements, thereby confirming skyrmion formation and quantifying the topological Hall resistivity at room temperature.
Contrary to the expectation that real-world surface roughness hinders structural superlubricity, this study demonstrates that nonuniform pressure distributions, particularly those with vanishing pressure at contact edges, actually enhance superlubricity by improving depinning and scaling behaviors to lower friction.
This study demonstrates that phase-controlled symmetry breaking of bound states in the continuum within a Majorana-quantum-dot nanostructure significantly enhances electronic thermoelectric performance, achieving a figure of merit of approximately 0.75 through superconducting-phase tuning and a pronounced violation of the Wiedemann-Franz law.
This theoretical study employs a variational effective mass model to demonstrate that quantum and dielectric confinement in CsPbBr nanocrystals of varying dimensionality (nanocubes, nanorods, and nanoplatelets) primarily enhance exciton binding energies and radiative recombination rates through wavefunction squeezing along strongly confined directions, while revealing that biexciton geometries consistently adopt a distorted tetrahedral shape across all systems.
This paper employs parquet renormalization group analysis to investigate the crossover from ordinary to higher-order van Hove singularities in honeycomb systems like bilayer and trilayer graphene, revealing how the merging of Fermi pockets and the resulting changes in density of states drive complex electronic ordering tendencies through the evolution, disappearance, and reemergence of renormalization group fixed points.
This study demonstrates that dipolar coupling between InP/ZnS quantum dots and carbon nanotubes in hybrid thin films creates a cross-dimensional excitonic platform where resonant Raman scattering reveals significant spectral shifts, intensity enhancements, and an effective splitting of approximately 110 meV that are not readily apparent in ensemble absorption spectra.
This study demonstrates single-shot laser-pulse-induced magnetization reversal in rare-earth-free CoFeB/MgO magnetic tunnel junctions by optimizing the Ru capping layer thickness, marking a significant step toward integrating ultrafast optical control with STT-MRAM technology.
This paper demonstrates that decorated Cayley trees, as tree analogs of specific two-dimensional lattices, exhibit flat energy bands that correspond to topological edge states of one-dimensional chains, revealing how non-Euclidean geometry alone can generate and stabilize unconventional quantum states.
This study investigates HgTe-based three-terminal Josephson junctions, revealing how the interplay between bias current and perpendicular magnetic fields enables tunable interference patterns, symmetry control, and strongly enhanced Josephson diode efficiency, with experimental findings quantitatively validated by resistively shunted junction simulations.
This study demonstrates that grain boundaries in free-standing nanocrystalline silicon membranes act as a frequency-dependent spectral filter that strongly suppresses high-order confined acoustic phonon modes through scattering rates scaling with , effectively distinguishing their behavior from that of crystalline silicon.
