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.
By employing Floquet flow-renormalization, this study reveals that periodically driven quantum many-body systems near dynamical freezing exhibit a universal approach to thermalization characterized by an unstable fixed point with emergent symmetry and a series of instanton events that significantly delay thermalization compared to conventional prethermal regimes.
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 study provides the first direct evidence of a tunable Quantum Anomalous Hall state with spontaneous ferromagnetism in twisted bilayer WSe2 by utilizing polarization-resolved attractive polaron spectroscopy to observe time-reversal symmetry breaking and confirm a Chern number of C=1.
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 theoretically demonstrates that altermagnet-based superconducting heterostructures can generate highly spin-polarized thermoelectric currents and achieve nearly perfect thermoelectric diode effects, offering significant potential for advanced spin-caloritronics applications.
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 proposes robust protocols using spatially local anyon injection at a single quantum point contact to isolate the universal anyonic statistical phase from nonuniversal interaction effects, deriving novel fluctuation-dissipation relations that allow for the direct experimental measurement of this phase via AC admittance or DC noise.
This paper demonstrates that within the Unified Nonequilibrium Perturbative framework, the anyonic exchange phase in Fractional Quantum Hall edges is fundamentally tied to Luttinger liquid scaling dimensions, yielding unique solutions for both Poissonian and super-Poissonian DC backscattering currents and noise through a derived nonequilibrium fluctuation-dissipation relation.
