This paper develops a theory of weak localization in graphene with Rashba spin-orbit interaction, demonstrating that the resulting anomalous magnetoresistance deviates from the traditional Hikami-Larkin-Nagaoka formula due to a unique spin-orbit vector potential and is applicable to graphene-transition metal dichalcogenide heterostructures.
This paper demonstrates that intrinsic plasmonic cavity modes formed by microstructured graphite gates in van der Waals heterostructures can ultrastrongly couple with graphene plasmons, enabling the manipulation of low-energy electrodynamics through on-chip THz spectroscopy despite sub-wavelength device dimensions.
This paper presents an analytical theory demonstrating that electrical spin orientation in magnetic two-dimensional heterostructures, such as spin-orbit coupled graphene and ferromagnet-proximitized semiconductors, exhibits a Hanle effect where the induced spin direction depends on out-of-plane magnetization and is highly sensitive to the specific type of electron elastic scattering.
This paper introduces Magnon Momentum Microscopy (MMM), a highly sensitive soft-X-ray technique that successfully images previously unobserved nonlinear magnon interactions at nanometre wavelengths in yttrium iron garnet, thereby establishing a versatile platform for exploring short-wavelength magnonics.
This study demonstrates that intrinsic van der Waals self-cavities in WTe induce Purcell enhancement of terahertz photogalvanic currents, establishing a geometry-tunable, bias-free mechanism for controlling nonlinear electronic responses in quantum materials.
This paper demonstrates that existing semiclassical theories, including Berry curvature dipole, side jumps, and skew scattering, fail to quantitatively match full quantum-mechanical results for the intraband circular photogalvanic effect in Weyl semimetals, indicating the necessity of incorporating additional microscopic mechanisms.
This paper develops a weak localization theory for graphene heterostructures with strong Rashba and valley-Zeeman spin-splittings, demonstrating that while valley-Zeeman splitting alone does not affect weak localization, its interplay with Rashba coupling and intervalley scattering can reverse the sign of the anomalous magnetoconductivity.
This paper proposes the edge spin galvanic effect in -wave altermagnets, where edge-aligned electrical currents are generated by spin-splitting and edge scattering, exhibiting sensitivity to edge orientation and Néel vector direction, while also predicting a pure spin edge photocurrent that can be converted into an electric current via an external magnetic field.
This paper demonstrates that rotating the boundary of bilayer graphene cavities relative to the underlying lattice induces a quantum transition from integrable to chaotic dynamics, a phenomenon confirmed through both full quantum analysis and semiclassical ray dynamics.
This paper derives semiclassical equations of motion for composite bound states in insulators and semiconductors, revealing that their dynamics are governed by a distinct quantum geometric dipole and a carefully chosen Berry curvature dependent on the composite's spatial center, leading to unique phenomena such as transverse drift and internal dipole oscillations in trions within magic-angle twisted bilayer graphene.
