This paper demonstrates that attention-based deep neural networks can effectively discover fractional Chern insulator ground states and extract their topological degeneracy through energy minimization, establishing neural network variational Monte Carlo as a powerful tool for studying strongly correlated topological phases without prior knowledge.
This paper establishes a general framework demonstrating that the Berry-curvature flux through the Fermi sea acts as an effective Aharonov-Bohm flux, driving a cascade of first-order transitions between chiral superconducting states with increasing angular momentum and inducing Little-Parks-like oscillations in the critical temperature.
This study demonstrates that orbital currents generated by the orbital Hall effect in chromium can be efficiently injected into terbium to induce a highly effective orbit-orbit torque (OOT) with a dampinglike efficiency of ~3.66, offering a promising pathway for manipulating orbital magnetization in orbitronics.
This paper investigates memory effects in two-dimensional nonequilibrium lattice systems using the NEGF and Schwinger-Keldysh frameworks to demonstrate how distinct scattering mechanisms (static disorder versus electron-phonon coupling) generate Markovian and Non-Markovian dynamics, respectively, which are identifiable through spectral function signatures and analyzed across various microscopic models.
This paper investigates wave transport in a two-dimensional aperiodic "Hat" monotile quasilattice using reconfigurable cavity-polariton optical lattices, confirming the existence of localized and critical states while revealing anomalous super-diffusive and near sub-diffusive transport regimes driven by the system's fractal structure.
This study employs molecular dynamics simulations with dynamic charge transfer to reveal that switching in Ta/HfO/Pt memristors is governed by the field-driven formation of hybrid filaments composed of both Ta cations and oxygen vacancies, demonstrating how initial defect configurations dictate filament morphology and offering a robust framework to reduce device variability.
This study reveals that multilayer magnetic topological insulator MnBi2Te4 exhibits dominant seventh-order nonlinear electronic transport linked to its magnetic phases, with quantum metric multipoles and nonlinear Drude conductivities identified as the underlying microscopic origins.
This study demonstrates that two-magnon scattering, rather than spin pumping alone, dominates the thickness-dependent Gilbert damping in YIG/V bilayers, necessitating a revised model to extract an accurate, thickness-independent effective spin-mixing conductance of .
This paper demonstrates that engineering geometrical boundary conditions, specifically by creating a chirality interface between double-helix nanowires, enables the deterministic generation and control of Bloch point spin textures with defined polarity, circulation, and helicity.
This study demonstrates that spatial magnetic inhomogeneities, specifically ferromagnetic domains and domain walls in a 75 nm-thick Fe0.5Pt0.5 film, produce macroscopically measurable conductivity modulations that significantly contribute to low-field magnetoresistance, particularly at low temperatures where their impact can exceed that of anisotropic terms.
