Advanced Optical Materials, EarlyView.Here, recent progress is highlighted in colloidal magnetoplasmonic hybrid nanomaterials, with a focus on chiral plasmonics. Metal nanocrystals with intrinsic chiroptical features can lead to a combination of chiral plasmonics and magneto‐optics effects when interacting with the magnetic counterpart, offering a foundation for systematically designing ...

Advanced Optical Materials, EarlyView.An optimized fabrication approach for the nanostructuring of optical metasurfaces from van der Waals materials like hexagonal boron nitride is presented. The resonator geometries show enhanced geometric homogeneity, resulting in a significant increase in quality factors of symmetry‐protected bound states in the continuum resonances.

On Euler number of symplectic hyperbolic manifold
Advances in MathematicsIn this article, we introduce a class of closed $2n$-dimensional almost Kähler manifold $X$ which called the special symplectic hyperbolic manifold. Those manifolds include Kähler hyperbolic manifolds. We study the spaces of $L^{2}$-harmonic forms on the universal covering space of $X$.

On Dual Hyperbolic Generalized Woodall Numbers
Archives of Current Research InternationalIn this work, we introduce the generalized dual hyperbolic Woodall numbers. As special cases, we study with dual hyperbolic Woodall, dual hyperbolic modified Woodall, dual hyperbolic Cullen numbers and dual hyperbolic modified Cullen numbers. Also, we present Binet’s formulas, generating functions, some identities, linear sums and matrices related with

Advanced Photonics Research, EarlyView.The images (a) and (b) illustrate a composite metamaterial with anisotropic permittivity. When incident light, polarized in transverse magnetic or transverse electric modes, enters the structure, the reflectance spectra in (c) and (d) show low reflection and high absorption over a wide range of incidence angles. This behavior has potential applications

Stimulated Raman Scattering with Optical Vortex Beams
Advanced Photonics Research, EarlyView.This study presents exact analytical expressions for stimulated Raman scattering with Laguerre‐Gaussian beams, revealing signal dependence on topological and hyperbolic momentum. The results provide a theoretical foundation for coherent Raman imaging and detecting orbital angular momentum of light via structured light in nonlinear optics.
