This paper investigates how localized Gaussian strain on a two-dimensional curved surface induces an attractive geometric potential and modifies the Fermi velocity for massless Dirac fermions, leading to the formation of bound states and localized Landau levels under an external magnetic field, thereby advancing the understanding of strain-induced electronic effects in materials like graphene.
This study demonstrates that coupling excitons in hexagonal boron nitride (hBN) and 2D perovskite heterostructures to defect networks enables ultralong-range energy transfer up to 150 micrometers, resulting in enhanced luminescence, stability, and performance for room-temperature optoelectronic applications.
This study demonstrates that compositional engineering of cylindrical magnetic nanowires creates dual-function sites that deterministically pin and actively gate Bloch-point domain walls by exploiting the interplay between long-range magnetostatic repulsion and short-range, circulation-dependent exchange interactions, thereby enabling controlled manipulation of both domain wall position and internal circulation for advanced spintronic applications.
This paper proposes a non-equilibrium Green's functions framework to simulate ultrafast laser-stimulated field emission from metallic nanotips, demonstrating how electron-electron correlations and dynamic optical back-action significantly reshape the emitted electron spectrum through the filtering of local density of states.
Using parton theory, this study reveals that while most paired composite-fermion states in even-denominator fractional quantum Hall systems host Abelian bound quasiparticles that obscure non-Abelian statistics, the state in wide quantum wells uniquely supports free quasiparticles, making it a prime candidate for realizing non-Abelian braid statistics.
This paper demonstrates that an hBN-encapsulated graphene double quantum dot functions as a solid-state two-level system with a tunable THz transition frequency, offering a scalable platform for future THz quantum technologies and the exploration of ultra-strong light-matter interactions.
This paper demonstrates that two-dimensional chiral Lifshitz fermions exhibit a half-quantized anomalous Hall response proportional to their winding number , establishing them as a higher-order generalization of the parity anomaly that remains distinct from quantum anomalous Hall insulators even when the conductivity is integer-quantized.
This paper demonstrates that a large-area graphene multiterminal Josephson junction exhibits a pronounced negative differential longitudinal resistance arising from the interplay between nonlocal Josephson coupling and nonlocal normal-state conductance, offering a new platform for characterizing hybrid superconductor-semiconductor systems and exploring many-body ground states.
This paper proposes an on-site quench protocol in atomic lattices that utilizes a two-dimensional flat-band bath to selectively remove dispersive excitations, thereby enabling the extraction of flat-band quantum geometry and integrated quantum distances through the analysis of late-time local occupation patterns.
This paper establishes a quantitative link between chemical bonding motifs and the quantum geometric tensor of electronic states, demonstrating how specific bonding patterns—such as noncollinear three-center bonds—dictate momentum-space textures, Berry curvature, and electromagnetic responses in materials.
