Generation of Optical Quasiparticles with Spin–Orbit Conversion in a Single Q‐Plate
Laser &Photonics Reviews, EarlyView.Spin‐Orbit conversion approach with a q‐plate for generating optical quasiparticles. ABSTRACT In this work, we detail a novel approach which can be used for the generation of optical quasiparticles. This process leverages both spin‐orbit conversion control with wavelength de‐tuning in a commercially available q‐plate.

Dipole‐Quadrupole Model and Multipole Analysis of Resonant Membrane Metasurfaces
Laser &Photonics Reviews, EarlyView.Membrane metasurfaces, arrays of holes in a dielectric membrane, are appealing because they require no substrate and allow access to resonant near‐fields. However, developing a comprehensive theoretical description for them remains challenging. We introduce a semi‐analytical dipole‐quadrupole approach to analyze their resonant spectra at arbitrary ...

On the Regular Integral Solutions of a Generalized Bessel Differential Equation
Advances in Mathematical Physics, 2018 The original Bessel differential equation that describes, among many others, cylindrical acoustic or vortical waves, is a particular case of zero degree of the generalized Bessel differential equation that describes coupled acoustic-vortical waves.

Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics
Laser &Photonics Reviews, EarlyView.The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.

Mathematische Nachrichten, EarlyView.Abstract This paper is devoted to the approximation of two‐ and three‐dimensional Dirac operators HV∼δΣ$H_{\widetilde{V} \delta _\Sigma }$ with combinations of electrostatic and Lorentz scalar δ$\delta$‐shell interactions in the norm resolvent sense. Relying on results from Behrndt, Holzmann, and Stelzer‐Landauer [Math. Nachr.

Extension of Oppenheim's Problem to Bessel Functions
Journal of Inequalities and Applications, 2007 Our aim is to extend some trigonometric inequalities to Bessel functions. Moreover, we deduce the hyperbolic analogue of these trigonometric inequalities, and we extend these inequalities to modified Bessel functions.

Mathematical Methods in the Applied Sciences, EarlyView.A highly accurate numerical method is given for the solution of boundary value problem of generalized Bagley‐Torvik (BgT) equation with Caputo derivative of order 0<β<2$$ 0<\beta <2 $$ by using the collocation‐shooting method (C‐SM). The collocation solution is constructed in the space Sm+1(1)$$ {S}_{m+1}^{(1)} $$ as piecewise polynomials of degree at ...

Analytical Modeling of Heat Transfer and Deformation Around a Circular Cavity in Elastic Ground
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT The subsurface is increasingly exploited to host energy, utilities, and infrastructure systems that interact with surrounding soils and rocks through their thermal and functional operation. Prominent examples are provided by energy geostructures, district heating networks, buried power cables, steam and water pipes, and underground nuclear ...
