This paper demonstrates that geometric curvature, controlled by the folding angle in a kagome lattice, acts as a continuous tuning parameter for topological magnon phases by establishing a curvature-dominated regime where bow-tie coupling surpasses Dzyaloshinskii-Moriya interactions, offering a unified mechanism for chirality-driven transport in systems where such interactions are symmetry-forbidden.
This paper demonstrates how identifying specific symmetries—namely effective time-reversal and particle-hole symmetries arising from sublattice symmetry—enables the classification and construction of generalized bosonic Kitaev chain models that exhibit non-Hermitian topological phenomena like skin effects.
This study demonstrates that the three-dimensional arrangement of polar vortices in ferroelectric PbTiO3/SrTiO3 superlattices significantly suppresses thermal conductivity through a mechanism distinct from standard interfacial scattering, offering a new strategy for actively modulating heat transport via complex polar superstructures.
This paper presents the design of lattice models with tailored quantum geometry that realize generalized Landau levels and ideal higher-Chern bands, demonstrating through exact diagonalization their capacity to host diverse fractional Chern insulators and other interaction-driven topological phases.
This study demonstrates a reversible method to dynamically tune charge transport in boron nitride-encapsulated graphene from a viscous hydrodynamic regime to an impurity-dominated regime at room temperature by using ultraviolet radiation to continuously modulate disorder levels in the hBN dielectric.
This paper theoretically demonstrates that periodically twisting a two-dimensional Aubry-André model induces a spatially varying multi-frequency drive that generates ring-shaped localized states with non-trivial topological signatures, shifting the focus from incommensurability to dynamical localization and hybridization.
This paper demonstrates that Richardson-Lucy deconvolution of scanning tunneling microscopy-induced luminescence images enables sub-diffraction-resolved mapping of exciton spatial distributions in 2D semiconductors like and , revealing critical dependencies on tunnel current and unexpected long-range emission from hot spots.
This study investigates device-dependent variability in ultra-clean graphene field-effect transistors, attributing resistance fluctuations to competing scattering mechanisms and contact coupling, while proposing a phenomenological analysis method to effectively extract viscous electronic contributions in high-mobility graphene.
This paper presents a simple, non-invasive, and scalable method for accurate on-chip thermometry in superconducting quantum circuits by integrating Dayem bridges alongside transmon qubits to directly measure local temperature and correlate it with qubit decoherence without requiring complex microwave calibration.
This paper proposes that the structural reconstruction of magic-angle twisted bilayer graphene from weak corrugation to large bending is driven by a twist-controlled mechanism called Moiré Phonon Condensation, where layer-symmetric flexural phonons soften and condense to capture the massive atomic displacements observed near the magic angle.
