Using a first-principles-based spin-spiral approach and atomistic spin models, this study predicts the emergence of diverse topological spin textures, including Néel-type skyrmions and bimerons, in an all-magnetic FeGeTe/CrGeTe van der Waals heterostructure driven by interfacial Dzyaloshinskii-Moriya interactions and geometric exchange frustration.
This paper reports the experimental realization and characterization of an individual V2+ ion embedded in a CdTe/ZnTe quantum dot, where polarization-resolved magneto-photoluminescence combined with numerical modeling confirms the system's properties and identifies its fundamental spin-1/2 state as a promising localized qubit.
This study demonstrates that alloying monolayer MoWSe semiconductors enables the engineering of extremely high excitonic -factors (up to -10) through non-trivial band structure modifications, as confirmed by both magneto-optical spectroscopy and first-principles calculations.
This paper theoretically demonstrates that a non-zero magnon thermal Hall effect can occur in collinear antiferromagnets at zero external magnetic field, driven by symmetry-breaking mechanisms such as sublattice asymmetry in compensated Néel order or Dzyaloshinskii-Moriya interactions in weak ferromagnets, and proposes a model where an external electric field can modulate this effect by altering the system's symmetry.
This paper proposes using microwave absorption visibility in cavity-coupled nanowires as a robust probe to distinguish nonlocal Majorana bound states from trivial zero-energy modes, based on the distinct requirement that true Majoranas only yield finite visibility when both ends are simultaneously coupled to the cavity.
This paper presents a comprehensive theoretical framework combining an 8-band model, continuum elasticity, and configuration interaction to accurately compute the electronic and emission properties of Coulomb-correlated multi-particle states in weakly confining GaAs quantum dots, demonstrating that a beyond-dipole formulation yields radiative lifetimes in quantitative agreement with experimental data.
This paper develops a symmetry-adapted multipolar theory for noncentrosymmetric crystals in the strong spin-orbit coupling limit, revealing that multipolar interactions for reshape Fermi surfaces and create distinct total-angular-momentum textures that lead to nonmonotonic, enhanced Edelstein effects in heavy-element materials.
This paper theoretically predicts that the Dzyaloshinskii-Moriya interaction induces a magnon equilibrium spin current in collinear antiferromagnets—an effect analogous to superconducting supercurrents that is large enough to be experimentally observable via magnon interference in a ring geometry under an external electric field.
This paper demonstrates that smooth spatial variations of the Néel order in altermagnets act as emergent gauge fields to induce strong, tunable in-plane anisotropies in electrical conductivity and linear dichroism, providing direct optical and transport probes for spin-textured states without requiring intrinsic spin-orbit coupling.
Motivated by recent twisted MoTe experiments, this paper develops a disordered interacting edge theory for a fractional topological insulator, revealing distinct conductance phases and an interaction-induced insulating state that demonstrates the insufficiency of two-terminal transport measurements for identifying such systems.
