This review article provides a comprehensive overview of the localized surface plasmon resonance properties and potential applications of various non-noble metal nanoparticles, comparing them to traditional noble metals like gold and silver.
This paper analyzes the nonlinear Hamiltonian dynamics of a transverse magnetic island chain to characterize various static domain wall structures, including those exhibiting antiferromagnetic order, which could be leveraged for sensitive detection and switching applications.
This paper proposes that thermovoltage, Seebeck coefficient, and various noise measurements (including the novel noise) can reliably distinguish between and pairing symmetries in iron-based superconductors by revealing distinct qualitative features such as twin-peak versus single-peak structures and sign reversals.
This paper presents a unified micromagnetic study of surface acoustic wave-driven spin wave dynamics in CoFeB films, demonstrating that the orientation of magnetic anisotropy acts as a tunable parameter to optimize resonant coupling, particularly when the wave propagates parallel to the external magnetic field.
This paper investigates the impact of interband transitions on the Faraday rotation of metallic nanoparticles by developing a quantum model for the dielectric function under a DC magnetic field and validating the theory against experimental measurements of gold nanoparticles, demonstrating that these transitions significantly influence optical properties in the blue and ultraviolet regimes compared to simpler Drude models.
This paper establishes a direct analytical and numerical link between strained graphene and the quantum Hall effect in curved space by deriving a second-order low-energy Hamiltonian, demonstrating excellent agreement between tight-binding calculations and curved-space predictions for Landau levels under constant pseudo-magnetic fields and curvature, and proposing experimental schemes to observe this phenomenon.
The authors propose a new -wave paired composite-fermion electron-hole trial wavefunction for quantum Hall bilayers at filling factor that demonstrates excellent agreement with exact diagonalization results across all interlayer separations and elucidates the crossover between large and small separation regimes as analogous to the BEC-BCS transition.
Using scanning tunneling microscopy and Hartree-Fock theory, this study demonstrates that doping-induced alignment of step-edge channels in PbSnSe with the Fermi level triggers a correlation gap, revealing how enhanced one-dimensional interactions intertwine with topological crystalline properties.
This paper introduces two single-parameter variational wavefunctions that accurately describe the ground state of bilayer quantum Hall systems across all separation values and provides the first numerically exact composite fermion representation of the Halperin-111 state.
This paper precisely determines the metastable remanent states and analyzes the oscillation modes of square artificial spin ice by incorporating all long-range dipole interactions, ultimately identifying stability limits based on the ratio of local anisotropy to dipolar coupling strength.
