Webmoments induced by fields incident on a chiral particle are d=α eE+iχH and m=α mH−iχE,whereα e and α m are the elec-tric and magnetic polarizabilities (16). The chiral polarizability of the particle χ captures the chiral nature of the dipole, such that setting χ=0 recovers the case of an achiral dipole. It is
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 two is called … 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.
