This study demonstrates an all-optical spin pumping method in a Ge-on-Si heterostructure that overcomes silicon's inherent limitations to achieve a record-high 9% spin polarization degree, thereby enabling the optical exploitation of silicon's spin-dependent properties for quantum and spintronic applications.
This paper derives simple expressions for time-dependent tunneling current in adiabatic regimes with finite-bandwidth reservoirs, defining a physically consistent tunneling time that reveals an intrinsic delay persisting even in static barriers and aligns well with optical experimental data.
This paper employs a linear hydrodynamic model to derive an analytical expression for electron energy loss in sub-5-nm metallic nanoparticles, revealing that penetrating electron beams can efficiently excite confined bulk plasmons with size- and impact-parameter-dependent spectral blueshifts and selection rules that are inaccessible to local dielectric frameworks.
This study utilizes time-resolved microwave measurements to demonstrate that the scattering of first-order azimuthal spin waves into vortex gyration and Floquet spin waves occurs via a three-wave splitting mechanism, characterized by a synchronous emergence of these modes after a power-dependent incubation delay that diverges at the scattering threshold.
This paper theoretically demonstrates that spin-orbit coupling induces avoided crossings in the dispersion relation of spinful Josephson junctions, leading to pronounced multiple Andreev reflection features in the subharmonic gap structure whose visibility under an external magnetic field is governed by the spin polarization of the bands.
This study utilizes lab-based Dark-Field magneto-optical Kerr effect magnetometry, supported by micromagnetic simulations and X-ray data, to characterize the magnetization reversal mechanism of double-helix nanowires as being mediated by the nucleation and propagation of helical vortex tubes, thereby demonstrating a viable alternative to large-scale facilities for probing 3D magnetic nanostructures.
This paper demonstrates that Transonic Flow Focusing (TFF) is a purely mechanical, surfactant-free method capable of efficiently exfoliating graphene nanoplatelets into high-purity monolayer graphene and nanofragments by leveraging extreme shear and elongational stresses in a contact-free zone.
Using diffusion quantum Monte Carlo simulations, this study characterizes the phase diagram of a mass-asymmetric one-dimensional electron-hole biwire at zero temperature, revealing that strong correlations drive excitonic quasicondensation even at high densities down to a.u., alongside distinct plasma and Wigner-correlated phases.
This paper establishes a fundamental connection between quantum error correction and mesoscopic physics by demonstrating that the statistical properties of post-measurement logical states in surface codes under uniform Pauli- rotations are isomorphic to chaotic scattering matrices in quantum dots, thereby revealing a universal random-matrix ensemble governed by Altland-Zirnbauer symmetry classes.
This paper proposes that a Hermitian ordering correction to the Dirac Hamiltonian in magic-angle twisted bilayer graphene generates an emergent Aharonov-Bohm flux, resulting in a predicted asymmetric double-peak spectral signature at AB/BA stacking points that explains existing discrepancies between STM data and standard theoretical models.
