This paper demonstrates a scalable, universal method for reconstructing infrared light intensity and polarization using conventional gated graphene-metal photodetectors, where gate-tunable polarization contrast enables single-device polarimetry across various junction geometries and graphene qualities.
This study reveals that ferromagnetic-based magnetoreception is widespread across diverse bee species and non-bee outgroups without phylogenetic signal, while its strength correlates with increased body size and social behavior.
This study reveals that in a non-Hermitian Su-Schrieffer-Heeger chain, the competition between the skin effect and Aubry-André-Harper quasiperiodic disorder generates a unique reentrant delocalization regime and distinct five-phase landscape, while simultaneously destroying point-gap topology and suppressing entanglement entropy.
This paper reviews the physics and mathematics of non-Hermitian disordered systems, with a focus on non-Hermitian random matrix theory, covering their 38-fold symmetry classification, spectral statistics, applications to chaos in open quantum systems, disorder-induced criticality, and effective field theory descriptions.
This paper proposes and theoretically validates a gate-tunable synthetic antiferromagnet based on a graphene/MnS/graphene heterostructure, where breaking structural symmetry induces dominant nonrelativistic spin splitting and giant magnetoresistance, offering a promising platform for efficient spintronic devices.
This paper presents a geometrically robust and computationally efficient cellular automaton model for simulating thermal transport in low-dimensional nanostructures across various regimes, successfully validated on graphene nanoribbons to capture critical scattering effects with linear scalability.
This study reveals that in twisted bilayers of loop-current-ordered kagome lattices, strong interlayer hybridization driven by twist induces a reconfiguration of quantum geometry that suppresses the monolayer's Berry curvature, thereby establishing these systems as unique platforms for exploring unconventional quantum geometry in moiré flat bands.
This paper establishes a mechanism for engineering quantum geometry in moiré flat bands beyond the valley paradigm by demonstrating that sublattice-selective interlayer tunneling in twisted bipartite heterobilayers induces isolated, tunable flat bands with finite Berry curvature and a Chern-insulator-scale quantum metric.
This paper proposes and validates through calculations that doping transition metal dichalcogenides (specifically V-doped WSe2 and WS2) near the valence-band edge induces band inversion via strong spin-orbit coupling, creating Chern insulators with non-zero Chern numbers that offer a promising platform for realizing the quantum anomalous Hall effect.
This paper introduces a tunable two-dimensional model of Dirac fermions in graphene that connects uniform Lorentzian barriers to chains of scatterers, demonstrating that super-Klein tunneling, scale invariance, and potential invisibility naturally arise from the system's intrinsic link to free-particle dynamics via supersymmetric quantum mechanics.
