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.
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 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.
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.
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 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 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 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 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 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.
