This paper demonstrates that spin inertia, when coupled with angular-momentum-breaking interactions like pseudodipolar forces in a honeycomb ferromagnet, hybridizes precessional and nutational magnons to open topological gaps and generate chiral edge states, establishing a new route for engineering topological phases in magnetic materials.
This study presents a first-principles analysis of the multiband superconductor BeAu, revealing its complex Fermi surface topology with high-Chern-number Weyl points and surface Fermi arcs, which supports a topological superconducting phase and potentially explains its multigap behavior.
This study employs first-principles calculations to demonstrate that the MoTe2/CrSBr van der Waals heterostructure features a stable type-II band alignment and a built-in electric field that collectively enable the formation of interlayer excitons with significantly extended lifetimes (18–45 ps), positioning it as a promising platform for next-generation optoelectronic applications.
This paper demonstrates that absolute negative mobility, a paradoxical phenomenon where a system moves opposite to an applied force, can occur in a minimal one-dimensional overdamped system driven by active Poisson shot noise within a symmetric periodic potential, offering new insights into biological transport and microscopic separation strategies.
This paper proposes a refined classification of magnetic textures using differential geometry by introducing geodesic and torsional scalar spin chiralities to fully characterize noncoplanar states, and demonstrates that the geodesic scalar spin chirality induces novel emergent band asymmetry and nonreciprocal responses as a purely orbital quantum geometric effect.
This study demonstrates that stacking misfit layered chalcogenides with 1H-TaS induces anisotropic symmetry breaking in the charge-density wave state through a nonlinear coupling with the uniaxial moiré potential, while leaving the material's s-wave superconductivity largely unaffected.
By combining high-resolution scanning tunneling microscopy with density functional theory, this study reveals that Fe-site ordering in the van der Waals ferromagnet FeGeTe drives nanoscale electronic phase separation, where ordered Fe(1) domains exhibit metallic behavior while deficient regions display pseudogapped states due to symmetry-allowed Fe 3d-Te 5p orbital hybridization.
This paper establishes a unified framework in altermagnets, specifically identifying monolayer V2STeO and VO families, where a gate-tunable potential enables the electrical switching between robust helical and chiral topological transport phases via spin-valley-momentum-locked edge states.
This study demonstrates that periodically driven linearly polarized light can uniquely induce an anomalous Hall effect and drive topological phase transitions in altermagnetic topological insulators by breaking their intrinsic symmetries, a phenomenon absent in conventional antiferromagnets, thereby offering a robust method for distinguishing these materials and enabling dissipationless spintronic applications.
This paper utilizes a direct phase-resolved optical technique to image the coherent excitation of spin waves in a CoFeB waveguide driven by surface acoustic waves via resonant magnetoelastic coupling, successfully separating the two signals through their distinct polarization dependencies.
This paper presents a tight-binding and nonequilibrium Green's function-based device simulator for 2-D topological insulator field-effect transistors, demonstrating how channel length affects performance and elucidating nontraditional switching mechanisms driven by gate-induced topological phase transitions.
This paper presents a theoretical framework demonstrating that hexagonal multiferroic media support electrically tunable nonlinear magnetoelastic solitons and breathers, where strong magnon-phonon hybridization leads to coherent, bounded dynamics rather than chaos, enabling precise control over soliton properties via external electric fields.
This paper presents an analytical treatment of chiral Majorana edge modes in quantum anomalous Hall insulator-superconductor heterostructures with shifted chemical potential, revealing that nonlinearity in the energy dispersion can induce a twisted, braid-like band structure that breaks chirality and enables bidirectional propagation.
Motivated by recent experiments on CsTiBi and RbTiBi, this study demonstrates that the next-nearest-neighbor hopping integral () acts as a critical control parameter by modulating the hybridization gap to either suppress or enable magnetic breakdown, thereby determining whether the intrinsic nontrivial Berry phase of the kagome lattice is observable in quantum oscillations.
This study demonstrates that a gate-tunable p-n heterojunction between the Dirac semimetal CdAs and the ferromagnetic semiconductor InMnAs enables efficient control of the Curie temperature via modest electric fields, revealing a novel interplay between topology and magnetism that extends beyond conventional hole-mediated mechanisms.
This paper demonstrates high-fidelity (99.8%) bucket-brigade spin shuttling in a silicon MOS device and reveals that residual errors are highly sensitive to the ratio between interdot tunnel coupling and Zeeman splitting, a relationship validated by a four-level Hamiltonian model to guide future quantum architecture optimization.
This paper demonstrates that the spin-1 AKLT Hamiltonian can be realized in tunable quantum-dot arrays by deriving an effective bilinear-biquadratic spin model from half-filled Hubbard tripods, where specific hopping parameters and coupling geometries yield the characteristic singlet-triplet degeneracy while suppressing unwanted longer-range interactions.
This paper establishes that the late-time dynamical scaling of strong-to-weak spontaneous symmetry breaking in one-dimensional open quantum systems is universally controlled by the symmetry class of the Lindbladian rather than its spectral gap structure, resulting in exponential growth of the Rényi-2 correlation length for symmetry and algebraic, filling-dependent scaling for U(1) symmetry.
This paper presents a theoretical framework demonstrating that hyperbolic phonon polaritons in anisotropic 2D materials, such as -MoO, can mediate and enhance long-range, highly directional mid-infrared energy transfer between dipoles at room temperature, extending interactions far beyond the near-field limits of conventional platforms.
This paper reports the experimental realization and modeling of a tunable triple-antidot molecule hosting interacting quantum Hall quasiparticles, where measured conductance spectra reveal molecular energy levels that align with a theoretical tunneling model, thereby establishing a foundation for studying complex systems with non-trivial quantum statistics.
