This paper demonstrates that in a minimal tight-binding model of a single helical chain, chirality alone—without atomic spin-orbit coupling—generates momentum-dependent orbital angular momentum textures and currents, leading to a robust orbital Edelstein effect and enhanced spin polarization via orbital-to-spin transduction.
This paper proposes that lattice relaxation-induced strain fields in rhombohedral graphene stacks aligned with hBN play a crucial role in flattening and isolating a valley-polarized Chern band with , challenging conventional views by highlighting the intertwined effects of long-range Coulomb interactions and structural relaxation in stabilizing topological states.
This paper proposes an electronic Lévy glass using graphene nanoribbons with tunable Rashba spin-orbit coupling regions, demonstrating that such a system exhibits a transition from superdiffusive to diffusive charge transport and multifractal charge dynamics only in the superdiffusive regime, while maintaining multifractal spin polarization across both regimes, thereby enabling control over electronic transmission and spin polarization via Fermi energy.
This paper demonstrates that threading exceptional points across the Brillouin zone boundary in gapped non-Hermitian systems annihilates them to form non-trivially closed branch cuts, thereby establishing distinct topological configurations of complex energy spectra that can only be interchanged by closing the spectral gap.
This study introduces AM-DefectNet, a comprehensive framework that benchmarks 15 machine learning models for additive manufacturing defect classification, revealing that the CatBoost algorithm outperforms others with 92.47% accuracy in melt pool characterization.
This study enhances Powder-Mixed Electrical Discharge Machining (PMEDM) with vibration by comparing four machine learning models to identify XGBoost as the most accurate predictor and subsequently employing Multi-Objective Evolutionary Algorithms to optimize the Pareto frontier for superior process efficiency and precision.
This paper proposes a coupled-wire construction for non-Abelian higher-order topological phases, demonstrating a minimal model of a non-Abelian second-order topological insulator where hybridized corner states are protected by a unified topological vector combining non-Abelian quaternion charges and Abelian winding numbers, thereby bridging distinct topological classes and suggesting experimental realizations in synthetic quantum systems.
This paper reveals that a detuned, driven two-level system exhibits exact quasienergy crossings at specific detunings due to a hidden time-nonlocal parity symmetry, which classifies Floquet modes and enables a general numerical scheme for its computation.
This paper reveals the existence of gapless symmetry-protected topological phases (gSPTs) in one-dimensional non-Hermitian Floquet systems, establishing a unified topological characterization via winding numbers on the generalized Brillouin zone that guarantees robust edge modes even at critical points.
This paper systematically constructs generalized lattice model wave functions for Laughlin, Moore–Read, and Read–Rezayi fractional quantum Hall states using analytical and numerical methods, revealing their distinct clustering behavior and providing a constructive framework for engineering topological orders in cold-atom and synthetic flat-band platforms.
