We study the single-photon transport in the scheme composed by N two-level atoms chirally coupled to N + 1 one-dimensional waveguides. The single-photon transport property relates to the chirality and the interference resulting from the scattering. The outcomes provide the potential applications for the optical quantum net and the ...
A chiral phenomenon is one that is not identical to its mirror image (see the article on mathematical chirality). The spin of a particle may be used to define a handedness, or helicity, for that particle, which, in the case of a massless particle, is the same as chirality. A symmetry transformation between the … See more The helicity of a particle is positive (“right-handed”) if the direction of its spin is the same as the direction of its motion. It is negative (“left-handed”) if the directions of spin and motion are opposite. So a standard See more Vector gauge theories with massless Dirac fermion fields ψ exhibit chiral symmetry, i.e., rotating the left-handed and the right-handed components … See more • To see a summary of the differences and similarities between chirality and helicity (those covered here and more) in chart form, one may go to Pedagogic Aids to Quantum Field Theory and click on the link near the bottom of the page entitled "Chirality and … See more Particle physicists have only observed or inferred left-chiral fermions and right-chiral antifermions engaging in the charged weak interaction.

Webhelicity states respectively. Hence, we have the physical interpretation for the chirality operator: The chirality or handedness is the same as the helicity operator when the particle mass is zero or it can be neglected. The operators PLand PR are commonly referred as left handed and right handed projection operators. Projection Operator Summary:
