Vector Beams with Only Transverse Intensity at Focus
Applied Sciences, 2023 In this work, the tight focusing of vector beams with azimuthal polarization and beams with a V-line of polarization singularity (sector azimuthal polarization) was simulated numerically using the Richards–Wolf formulas.

Singularities of divisors of low degree on abelian varieties [PDF]
, 2005 Building on previous work of Kollar, Ein, Lazarsfeld, and Hacon, we show that ample divisors of low degree on an abelian variety have mild singularities in case the abelian variety is simple or the degree of the polarization is two.Comment: Minor ...

Depolarization of Vector Light Beams on Propagation in Free Space
Photonics, 2022 Nonparaxial propagation of the vector vortex light beams in free space was investigated theoretically. Propagation-induced polarization changes in vector light beams with different spatial intensity distributions were analyzed.

On surfaces with p_g=q=2, K^2=5 and Albanese map of degree 3 [PDF]
, 2012 We construct a connected, irreducible component of the moduli space of minimal surfaces of general type with $p_g=q=2$ and $K^2=5$, which contains both examples given by Chen-Hacon and the first author. This component is generically smooth of dimension 4,

On Some Recent Ideas on the Proton Radius Puzzle and Lepton Anomalous Magnetic Moments [PDF]
, 2014 We discuss recent suggestions on the resolution of the proton radius puzzle put forward in [1,2] and discovery of a nonperturbative quantum-electrodynamic contribution of order $(\alpha/\pi)^5$ to lepton anomalous magnetic moments announced in [3,4].

Polarization singularities in light scattering by small particles [PDF]
, 2020 Using full-wave numerical simulations and analytical multipole expansions, we investigated the properties of real-space polarization singularities that emerge in light scattering by subwavelength particles.

Polarization singularity anisotropy: determining monstardom [PDF]
Optics Letters, 2008 C points, that is isolated points of circular polarization in transverse fields of varying polarization, are classified morphologically into three distinct types, known as lemons, stars and monstars. These morphologies are interpreted here according to two natural parameters associated with the singularity, namely the anisotropy of the C point, and the

Creating and Controlling Polarization Singularities in Plasmonic Fields
Photonics, 2015 Nanoscale light fields near nanoplasmonic objects can be highly structured and can contain highly-subwavelength features. Here, we present the results of our search for the simplest plasmonic system that contains, and can be used to control, the smallest

DVCS amplitude with kinematical twist-3 terms [PDF]
, 2000 We compute the amplitude of deeply virtual Compton scattering (DVCS) using the calculus of QCD string operators in coordinate representation. To restore the electromagnetic gauge invariance (transversality) of the twist-2 amplitude we include the ...
