Web2. The helicity λ is invariant under rotations and so states can be con-structed with definite J and helicities. 3. The helicity λ is well defined also for massless particles and so there is no need for separate treatment for massless particles. 4. The helicity states are directly related to individual polarization prop- WebAbstract Considering time-harmonic optical fields, we put forward the complex helicity and its alternating flow, together with their conservation equation: the complex helicity theorem. Its imaginary part constitutes a novel law that rules the build-up of what we establish as the reactive helicity through its zero time-average flow.

WebJun 16, 2024 · We show that a zero total reactive helicity - i.e. internal plus external - underlies a resonant scattered helicity. These reactive quantities are shown to yield a novel interpretation of the two Kerker conditions which we demonstrate to be linked with an absence, or minimum, of the overall scattered reactive energy.
