This paper analyzes the quantum and topological properties of graphene-based plasmonic systems across various materials, including single-layer and twisted bilayer graphene, and diverse architectures such as gratings, grids, disk chains, and kagomé lattices.
This review article synthesizes the multifractal characteristics of the non-Hermitian skin effect across single-particle, many-body, and tree models, highlighting the unique multifractality and ergodic properties of the many-body skin effect and providing an analytically solvable Cayley tree model to describe these phenomena.
This paper demonstrates that silver-coated polystyrene microsphere monolayers using ~200 nm colloids function as effective surface plasmon resonance sensors in both transmission and reflection modes, revealing a highly sensitive secondary transmission band and confirming that the reflection configuration offers superior sensing efficiency compared to transmission.
This paper demonstrates that Hahn echo measurements in electron spin resonance scanning tunneling microscopy (ESR-STM) are often misinterpreted as intrinsic spin coherence times because they are dominated by RF-voltage-induced relaxation, and it proposes a modified pulse protocol to reliably extract the true, significantly shorter coherence time of approximately 30 ns.
This paper establishes that three-dimensional -symmetric insulators characterized by the topological invariant support a corresponding number of chiral hinge modes at surface domain walls, distinguishing these phases from stacked Chern insulators through the derivation of effective surface Hamiltonians and numerical tight-binding model demonstrations.
This paper investigates the optical properties of linear arrays of silver-coated polystyrene microspheres as hybrid plasmonic-photonic crystals, demonstrating their spectral tunability, polarization-sensitive response, and potential for surface-enhanced Raman scattering applications.
This paper demonstrates that shear strain-induced spin-group-symmetry breaking in collinear altermagnetic insulators enables sign-controlled charge and spin photocurrents via spin-gap asymmetry, offering a novel optical method to detect and investigate altermagnetism.
The paper introduces the Majorana-XYZ subsystem code, a new quantum error correction scheme derived from Majorana fermions on a honeycomb lattice that utilizes 3-local nearest-neighbour checks to protect a macroscopic number of logical qubits through topologically non-trivial degrees of freedom while confining undetected errors to the gauge group.
This paper presents a conditional diffusion model that efficiently reconstructs full quantum dot charge stability diagrams from as little as 4% of sparse measurements, significantly accelerating device characterization compared to traditional interpolation methods.
This study reports the observation of a highly enhanced, anomalous nonlinear magnetoconductivity in van der Waals CrSBr/hBN heterostructures, which arises from Berry connection polarizability and enables magnetically switchable, high-frequency rectification and efficient electrical readout of magnetic states.
