Journal ArticleDOI
Optical helicity, optical spin and related quantities in electromagnetic theory
TL;DR: In this paper, the authors examined the optical helicity, the optical spin and the ij-infra-zilches in electromagnetic theory and showed that these conserved quantities can be combined to form a new description of the angular momentum associated with optical polarization, analogous to the familiar description of optical energy and linear momentum.
Journal ArticleDOI
Discriminatory optical force for chiral molecules
TL;DR: In this paper, the force F exerted upon a chiral molecule by light assumes the form under appropriate circumstances, where a and b pertain to the molecule whilst w and h are the local densities of electric energy and helicity in the optical field; the gradients of these quantities thus governing the molecule's centre-of-mass motion.
Journal ArticleDOI
On the natures of the spin and orbital parts of optical angular momentum

TL;DR: In this paper, it was pointed out that the Laguerre-Gaussian modes, familiar from laser physics, carry orbital angular momentum, and the spin and orbital parts correspond to distinct symmetries of the free electromagnetic field and hence are separately conserved quantities.
Journal ArticleDOI
Duplex symmetry and its relation to the conservation of optical helicity
TL;DR: In this article, the relationship between the optical helicity and the more familiar optical spin was examined and it was shown that the conservation of helicity is an expression of the electric-magnetic symmetry for light.
Journal ArticleDOI
Electric–magnetic symmetry and Noether's theorem
TL;DR: In this paper, a variational description of the free electromagnetic field is proposed based on the acknowledgement of both electric and magnetic potentials, and the symmetry associated with the conservation of Lipkin's zilches is identified.
