This paper demonstrates that a noncollinear kagome antiferromagnet can generate unconventional alternating out-of-plane spin polarization and spin-polarized transport through magnetic symmetry and spatial confinement, even in the absence of relativistic spin-orbit coupling.
This paper demonstrates a native, gate-tunable flux-charge coupling in a hybrid superconducting-semiconductor fluxonium circuit by utilizing a parametrically modulated Josephson junction, thereby introducing a critical new primitive that enables the coherent interaction of conjugate variables in superconducting circuits.
This paper resolves the long-standing puzzle of the large negative thermal Hall effect in the cuprate pseudogap phase by demonstrating that the parity anomaly of preformed pairs yields a parameter-free formula linking the thermal Hall conductivity directly to the experimentally measurable pseudogap energy scale.
This paper introduces a novel platform for creating Moiré quantum dots by crossing 1D MoS₂ nanoribbons at various angles, demonstrating angle- and size-dependent tunability of exciton physics, including enhanced emission at specific commensurate angles and reduced exciton energy in smaller Moiré areas.
This paper demonstrates that increasing aluminum gate thickness induces strain in a silicon two-dimensional hole gas, leading to the emergence of a second subband and revealing distinct cyclotron masses that deviate from ideal heavy-hole/light-hole models due to the combined effects of quantum confinement, strain, and band mixing.
This paper demonstrates that magnetic skyrmions in a two-dimensional quasicrystalline lattice exhibit a unique, quasi-continuous tunability of density and emergent gauge fields under magnetic fields due to competition with a quasiperiodic pinning landscape, offering a distinct advantage over periodic lattices for controlling topological charge and Hall conductivity.
This paper analytically demonstrates that in a non-Hermitian Hatano-Nelson model with quasiperiodically modulated hopping, parameter regimes hosting critical eigenstates under periodic boundary conditions can exhibit the non-Hermitian skin effect under open boundary conditions, a phenomenon confirmed through exact Lyapunov exponent calculations and extended to long-range and multiband systems.
This paper experimentally demonstrates that caustic spin-wave beams in anisotropic yttrium iron garnet waveguides reflect via transitions between caustic points on the iso-frequency contour rather than following Snell's law, enabling continuous magnetic control over beam routing and steering.
This paper demonstrates that an external magnetic field applied to a monolayer WSe magnetic barrier enables precise, spin- and valley-dependent control over the Goos-Hänchen shift and group delay time, offering a tunable mechanism for spatial and temporal separation of electronic wave packets with applications in spintronic and valleytronic devices.
This paper constructs localized approximate eigenfunctions for Hamiltonians modeling aperiodic crystals, demonstrating that under specific assumptions on the associated periodic operator family, these functions yield energy estimates with a controlled error of order for small .
