Ukraine and singular optics [PDF]
Nanophotonics, 2023 The mostly theoretical viewpoint, in which light is understood in terms of its singularities – caustics, phase vortices and lines of circular and linear polarisation – was developed in Bristol in the 1970s and 1980s.

Linear Optics Calibration in a Storage Ring Based on Machine Learning
Applied Sciences, 2023 Inevitably, various errors occur in an actual storage ring, such as magnetic field errors, magnet misalignments, and ground settlement deformation, which cause closed orbit distortion and tuning shift. Therefore, linear optics calibration is an essential

Polarization singularities from unfolding an optical vortex through a birefringent crystal [PDF]
, 2004 Optical vortices (nodal lines and phase singularities) are the generic singularities of scalar optics but are unstable in vector optics. We investigate experimentally and theoretically the unfolding of a uniformly polarized optical vortex beam on ...

Kink and breather waves with and without singular solutions to the Zoomeron model
Results in Physics, 2023 The Zoomeron model is applied to various types of solitons arising in fluid mechanics, laser optics, and nonlinear physics. We derive analytical solutions to the mentioned model using the exp(−λ(ς))-expansion, the generalized Kudryashov, and the ...
