This paper proposes and demonstrates a method to experimentally access a quantized local Chern marker for topological magnons in a 2D ferromagnetic Heisenberg system by combining local driven-dissipative preparation with circular dichroism measurements, enabling the detection of bulk topological properties with single-site resolution while accounting for magnon losses.
This study demonstrates that field-driven ultrafast carrier saturation in gapless Dirac semimetals, specifically highly oriented pyrolytic graphite, significantly suppresses interband high-harmonic generation and induces temporal shifts, revealing a critical mechanism for probing ultrafast electron dynamics via two-color harmonic spectroscopy.
This paper introduces a scalable framework for modeling many-body interactions in surface-code quantum processors, revealing how residual crosstalk can invert interaction hierarchies and drive the system into a topologically ordered regime, thereby guiding the optimization of next-generation high-fidelity hardware.
By combining local thermodynamic and transport measurements in twisted trilayer graphene, the study reveals that superconductivity is not directly tied to correlated insulators but instead correlates closely with the strength of compressibility sawtooth features, suggesting a shared origin linked to electron-electron interactions and twist-angle-dependent band structures.
This paper proposes and validates a microscopic, weak-coupling mechanism where interacting electrons coupled to a Markovian Ohmic bath asymptotically relax toward ideal Chern bands, thereby providing a dissipative pathway to stabilize fractional Chern insulators by driving the system's quantum geometry toward saturation.
This paper predicts that the emergence of Abrikosov vortex clusters in the normal phase of type-II superconductors just above the critical field can be detected via a pronounced, measurable enhancement in the imaginary part of the microwave ac-conductivity, offering a new experimental signature for these previously unobservable quantum fluctuations.
This paper demonstrates a layer-engineered platform based on twisted rhombohedral graphene where the Chern number of the quantum anomalous Hall effect can be programmatically set by the layer configuration and dynamically tuned or switched via electrical fields, enabling the on-demand design of reconfigurable topological states.
This paper presents an expandable kinetic Monte Carlo platform designed to model and compare competing theories of electron transport through chiral molecules, specifically investigating the relationship between Electronic Magnetochiral Anisotropy (eMChA) and Chirality Induced Spin Selectivity (CISS) by simulating voltage-dependent spin filtering effects.
This paper establishes a quantitative framework for interpreting quantum Hall scanning-probe images by deriving a transport operator functional that distinguishes between thermal, electrical, and viscous contrasts, revealing that thermoelectric signals are pinned by energy weighting rather than defect geometry in strong fields and that Hall-odd images in hydrodynamic regimes require careful disentanglement of mixed transport channels.
This paper presents a post-processing pipeline to extract interconnection graphs from photomicrographs of silver nanowire networks, revealing that their experimental topologies exhibit small-world and modular characteristics while also analyzing how overestimation of junctions in zenithal-view images impacts key graph metrics like clustering coefficient and path length.
