Using time- and angle-resolved photoemission spectroscopy, this study demonstrates that exciting a WS₂-graphene heterostructure at the higher-energy C-exciton resonance accelerates ultrafast interlayer hole transfer by generating elevated carrier temperatures that open an additional, highly efficient charge-transfer channel.
This paper presents a first-principles framework that unifies electron and phonon hydrodynamics into coupled viscous thermoelectric equations, demonstrating how composite "relaxon" excitations govern non-diffusive transport and predicting distinct signatures of electron-phonon drag in complex device geometries.
This paper demonstrates that in hybrid superconductor-hole systems, the opposite mass signs between subsystems can paradoxically suppress proximity-induced superconductivity by enhancing insulating gaps at subband anticrossings, leading to a characteristic anomalous Josephson effect that is crucial for designing robust quantum computing platforms.
This paper proposes a shifted magnetic bilayer system with mutually orthogonal Dzyaloshinskii-Moriya interactions that supports "linked skyrmions"—magnetic solitons with arbitrary large topological charges formed by multiple skyrmions connected via anti-aligned point defects—alongside other complex configurations like skyrmion bags and -skyrmions, while identifying a suitable material candidate for their experimental realization.
This study demonstrates the formation of interlayer exciton condensates between second Landau level orbitals in double bilayer graphene, revealing that such states emerge only when the wavefunctions are polarized toward the hBN interface to maximize interlayer Coulomb interactions.
This paper proposes a regularized micromagnetic model that treats magnetization as an order parameter constrained to an S3-sphere, thereby resolving the divergence issues of classical theory at Bloch points and enabling the accurate description of their dynamics in various magnetic textures.
This theoretical study demonstrates that a nanoribbon with Rashba and Dresselhaus spin-orbit coupling exhibits resonant spin Hall and Nernst effects, as well as distinct signatures in longitudinal conductance, driven by intrinsic spin degeneracy and anticrossing points that emerge without the need for external perturbations like magnetic fields or light.
This paper investigates quantum localization in two coupled tight-binding chains with incommensurate periods, revealing a mobility edge and demonstrating that while weak magnetic fields enhance localization, strong fields tend to delocalize most states.
This study reveals that in a low-quality-factor planar microcavity, exciton-polariton linewidths exhibit counterintuitive spectral narrowing as detuning decreases, a phenomenon that challenges conventional constant-loss strong-coupling models and suggests the critical role of frequency-dependent self-energy or correlated dissipation effects.
This paper reports the successful fabrication and operation of a three-terminal field-effect device utilizing a flip-chip technique to preserve a pristine two-dimensional electron gas, achieving a record-breaking electron mobility exceeding 40 million cm²/(Vs) that doubles previous benchmarks and opens new avenues for quantum transport applications.
