The magnetic field of M31 from multi-wavelength radio polarization observations [PDF]
, 2003 The configuration of the regular magnetic field in M31 is deduced from radio polarization observations at the wavelengths 6, 11 and 20 cm. By fitting the observed azimuthal distribution of polarization angles, we find that the regular magnetic field ...

Singularity index and orbital angular momentum of a beam with a hybrid polarization singularity
Компьютерная оптикаAlongside scalar optical vortex beams, which have a topological charge (TC), a spiral wave front and carry an orbital angular momentum (OAM) that can be transferred to microparticles and rotate them along circular trajectories, polarization optical ...

Convective motions and net circular polarization in sunspot penumbrae
, 2009 We have employed a penumbral model, that includes the Evershed flow and convective motions inside penumbral filaments, to reproduce the azimuthal variation of the net circular polarization (NCP) in sunspot penumbrae at different heliocentric angles for ...

Azimuthally polarized surface plasmons as effective terahertz waveguides
Optics Express, 2005 Quite recently, it was found that metal wires can effectively guide terahertz radiation. Based on the fact that the absolute values of the relative permittivities of metals in the spectral region of terahertz radiation are huge, we here analyse the properties of this kind of waveguide and explain the related experimental results. In particular, we show

European Physical Journal C: Particles and Fields, 2018 In this paper we indicate a possibility of utilizing the elastic scattering of Dirac low-energy ($$\sim 1$$ ∼1 MeV) electron neutrinos ($$\nu _e$$ νe s) on a polarized electron target (PET) in testing the time reversal symmetry violation (TRSV).

Polarization shaping for control of nonlinear propagation [PDF]
, 2016 We study the nonlinear optical propagation of two different classes of space-varying polarized light beams -- radially symmetric vector beams and Poincar\'e beams with lemon and star topologies -- in a rubidium vapour cell.

Probing the top Yukawa coupling at the LHC via associated production of single top and Higgs
Journal of High Energy Physics, 2020 We study Higgs boson production associated with single top or anti-top via t-channel weak boson exchange at the LHC. The process is an ideal probe of the top quark Yukawa coupling, because we can measure the relative phase of htt and hWW couplings ...
