Micro-focused ARPES and first-principles calculations reveal that RuO2 exhibits spin-degenerate bulk bands inconsistent with altermagnetism, while its observed surface states near the Fermi level arise from topological Dirac nodal lines, suggesting these features are crucial for understanding the material's spintronic and catalytic properties.
This paper proposes a two-dimensional magnetic model incorporating an inversion-symmetric (Skyrme) interaction term that stabilizes topologically protected magnetic skyrmions under strong external magnetic fields, addressing scenarios where conventional exchange interactions are overwhelmed by the Zeeman effect.
This paper presents an FPGA-powered real-time adaptive protocol that overcomes traditional temporal resolution limits to track rapid fluctuations in superconducting qubit relaxation rates, revealing millisecond-scale switching events and fast two-level system dynamics that redefine calibration timescales and deepen the understanding of environmental decoherence.
This study employs large-scale first-principles calculations to reveal how atomic-scale wavefunction textures and interlayer interaction strength in magic-angle twisted bilayer graphene drive a topological phase transition involving band inversion, offering a theoretical framework to interpret experimental signatures of superconductivity and correlated phases.
This study investigates the twist-angle-dependent hybridization between flat and remote bands in twisted bilayer graphene, revealing multiple topological phase transitions driven by band inversions and identifying previously unreported states with Chern numbers up to two.
This paper proposes a mechanism for controlling magnetic Skyrmion motion by inducing a Skyrmion number current through the anisotropic breathing mode generated by circularly polarized light, offering a low-dissipation alternative to electric currents for efficient Skyrmion manipulation.
This paper proposes a coupled electric dipole model treating Si@Ag coreshell nanoparticles as multiple interacting dipoles to demonstrate that periodic Su-Schrieffer-Heeger chains of these nanostructures host multiple topological edge states pinned at the particles' resonant frequencies.
This paper theoretically demonstrates that in-plane magnetic fields induce hybridization between spin-bright and spin-dark excitons in transition metal dichalcogenide monolayers, leading to the brightening of dark excitons and complex spectral modifications characterized by energy shifts, broadening, and amplitude variations.
Magnetotransport spectroscopy of low-disorder GaAs/AlGaAs 2D hole gases reveals that many-body interactions enhance the effective masses of both Rashba-split heavy-hole subbands by a common factor of approximately 2.3, providing a cohesive framework that reconciles long-standing discrepancies between Luttinger theory, magnetotransport, and cyclotron resonance measurements.
This paper theoretically investigates the tunable nonlinear magneto-optical shift conductivity in the surface states of BiSe under perpendicular magnetic fields, demonstrating that the effect arises from discrete Landau level transitions and can be effectively controlled by adjusting the chemical potential and magnetic field strength.
