This study demonstrates the successful trapping and measurement of quasiparticles in even-denominator fractional quantum Hall states of bilayer graphene using a gate-defined antidot, providing strong evidence for non-Abelian ground states and a critical step toward topological quantum computation.
This paper establishes a geometric framework linking the local structure of electronic bands and Fermi surfaces to intrinsic spin transport, demonstrating how hyperbolic regions generate spin currents and how spin operators relate to the exterior algebra of momentum space.
This paper experimentally validates a capacitive method that directly detects quantized charge accumulation in a quantum anomalous Hall system, confirming the intrinsic relationship between Hall conductance and surface charge density under ultra-low dissipation conditions.
This paper proposes a simple regularization of the smooth quantum hydrodynamic model by substituting the electron density derivative with a classical Boltzmann distribution to eliminate unstable modes, thereby enabling time-dependent simulations of resonant tunneling diodes that accurately reproduce realistic negative differential resistance and hysteresis in agreement with fully quantum mechanical results.
This paper predicts and classifies interaction-driven quantum spin Hall crystals (QSHCs) emerging at fractional fillings in twisted MoTe, providing specific evidence for a 9-fold quasi-degenerate charge-ordered state at near a twist that exhibits distinct topological phases protected by time-reversal or valley symmetry.
This paper proposes the photonic spin-Hall effect as a non-invasive probe for time-reversal-symmetry broken band topological phases, demonstrating that the frequency-dependent sign structure of the centroid shift directly reveals the system's optical Hall conductivity and topological nature.
The study reveals that substituting Co into Fe4GeTe2 induces layer-selective ordering and enhanced electronic correlations of quasi-localized Co 3d-states, which drive an unusually high-temperature antiferromagnetic order at 250 K in the van der Waals material (Fe0.65Co0.35)4GeTe2, establishing it as a promising candidate for AFM spintronics.
This paper reports experimental signatures of a ferro-Josephson effect in twisted graphene, where current-driven precession of spin-domain-wall moments generates topological electromotive forces manifesting as sharp, field-dispersive resonances in longitudinal resistance at ultra-low energy scales.
This paper identifies metastable domains of orbital magnetism, driven by spin-valley coupling and sensitive to gate-voltage trajectories and in-plane magnetic fields, as the microscopic origin of the anomalous zero-field resistance peak observed in the valley-polarized quarter-metal state of twisted double bilayer graphene.
This paper extends the concept of topological Euler insulators to non-Hermitian systems by establishing a theoretical framework for their topological classification, bulk-boundary correspondence, and unique phase transitions in two-dimensional symmetric lattice models.
