Spin angular momentum associated with circular polarization is a fundamental and
important aspect of photons both in classical and quantum optics. The interaction of this …

Polarization singularities are superpositions of orbital angular momentum (OAM) states in
orthogonal circular polarization basis. The intrinsic OAM of light beams arises due to the …

An Up-to-Date Compendium on the Physics and Mathematics of Polarization Phenomena
Now thoroughly revised, Polarized Light and the Mueller Matrix Approach cohesively …

Publisher Summary The widespread availability of spatially and temporally coherent laser
sources makes the production of optical vortices inevitable in any experiment involving …

Bound states in the continuum in periodic photonic systems like photonic crystal slabs are
proved to be accompanied by vortex polarization singularities on the photonic bands in the …

The polarization singularity in momentum space has recently been discovered as a new
class of topological signatures of Bloch modes in photonic crystal slabs concerning the far …

" This engagingly written text provides a useful pedagogical introduction to an extensive
class of geometrical phenomena in the optics of polarization and phase, including simple …

INTRODUCTION Topology is the study of geometric properties that are unaffected by
continuous changes in shape and size. Skyrmions are examples of topological defects in …

For scalar light, the current is the familiar expectation value of the intensity-weighted
momentum operator. Current is distinct from the local wavevector (not weighted) that could …

Polarization singularities and topological polarization structures are generic features of
inhomogeneous vector wave fields of any nature. However, their experimental studies …
