Quantum corrections to the Schwarzschild metric from vacuum polarization [PDF]
Physical Review D, 2022 We explore static and spherically symmetric solutions of the 4-dimensional semiclassical Einstein's equations using the quantum vacuum polarization of a conformal field as a source.

Hilbert’s Hotel in polarization singularities
Optics Letters, 2017 We demonstrate theoretically how the creation of polarization singularities by the evolution of a fractional nonuniform polarization optical element involves the peculiar mathematics of countably infinite sets in the form of "Hilbert's Hotel." Two distinct topological processes can be observed, depending on the structure of the fractional optical ...

Polarization conversion when focusing cylindrically polarized vortex beams
Scientific Reports, 2016 Currently, cylindrical beams with radial or azimuthal polarization are being used successfully for the optical manipulation of micro- and nano-particles as well as in microscopy, lithography, nonlinear optics, materials processing, and telecommunication ...

Sharp focusing of a light field with polarization and phase singularities of an arbitrary order [PDF]
Компьютерная оптика, 2019 Using the Richards-Wolf formalism, we obtain general expressions for all components of the electric and magnetic strength vectors near the sharp focus of an optical vortex with the topological charge m and nth-order azimuthal polarization.

Physical Review Research, 2021 We theoretically investigate metasurface spatiotemporal dynamics by introducing laser chaotic dynamics into metasurface domain. The spatiotemporal dynamics takes advantage of both the time-dependent dynamics of optical chaos and the local spatial ...

Spin Hall Effect in the Paraxial Light Beams with Multiple Polarization Singularities
Micromachines, 2023 Elements of micromachines can be driven by light, including structured light with phase and/or polarization singularities. We investigate a paraxial vectorial Gaussian beam with multiple polarization singularities residing on a circle.

Photonics, 2023 The generation of Bessel beams (BBs) and their characterization in a wide range of the electromagnetic spectrum are well established. The unique properties of BBs, including their non-diffracting and self-healing nature, make them efficient for use in ...

Deformable polarization singularity array by superimposed Ince–Gaussian beams
Applied Physics LettersWe present a numerical and experimental study of polarization singularity arrays, which are generated by the coherent superposition of orthogonal, linearly polarized, even and odd Ince–Gaussian (IG) beams.
