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.
Using sign-free determinantal quantum Monte Carlo simulations, this study reveals that triangular-lattice M-point moiré materials with near- symmetry exhibit a unique intermediate-coupling regime characterized by hidden antiferromagnetism and persistent valley fluctuations arising from the competition between local-moment formation and itinerancy.
This paper demonstrates that short optical pulses induce dynamic, wave-like behaviors in the quantum metric and Berry curvature of graphene's Bloch states near Dirac points, generating measurable Fisher information waves that reflect the underlying Floquet-band structure.
Using the Keldysh non-equilibrium Green's function approach, this study reveals that long-range hopping in helical systems induces robust, plateau-like pumped dc currents controlled by the decay exponent and drive frequency, whereas short-range hopping yields more parameter-sensitive responses without such plateaus.
This paper establishes a rigorously self-consistent bidirectional magneto-thermal coupling model that integrates the stochastic Landau-Lifshitz-Gilbert equation with a generalized heat transfer equation to dynamically link magnetization dissipation and thermal fluctuations, thereby ensuring thermodynamic consistency and enabling the study of complex nonequilibrium spin-caloritronic phenomena.
