Scattering of Skyrmions
In this paper, we present a detailed study of Skyrmion-Skyrmion scattering for two B = 1 Skyrmions in the attractive channel where we observe two different scattering regimes. For large separation, the scattering can be approximated as interacting dipoles. We give a qualitative estimate when this approximation breaks down. For small separations we observe an additional short-range repulsion whi...
متن کاملTheory of helicoids and skyrmions in confined cholesteric liquid crystals.
Cholesteric liquid crystals experience geometric frustration when they are confined between surfaces with anchoring conditions that are incompatible with the cholesteric twist. Because of this frustration, they develop complex topological defect structures, which may be helicoids or skyrmions. We develop a theory for these structures, which extends previous theoretical research by deriving exac...
متن کاملLight scattering by cubical particle in the WKB approximation
In this work, we determined the analytical expressions of the form factor of a cubical particle in the WKB approximation. We adapted some variables (size parameter, refractive index, the scattering angle) and found the form factor in the approximation of Rayleigh-Gans-Debye (RGD), Anomalous Diffraction (AD), and determined the efficiency factor of the extinction. Finally, to illustrate our form...

متن کاملLight Refraction by a Cholesteric Prism
Light propagation in a cholesteric medium has been completely discussed by de Vries [2]. The main results are that, for a given frequency, there are two eigenvibrations with quasi-circular polarizations, except i) for high frequencies and ii) near the reflection band (for the vibration having total reflection), where the polarization is linear. Looking at light refracted by a cholesteric prism,...
