Reactive helicity
WebJun 16, 2024 · reactive helicity may be experimentally observed as we introduce a reactive spin momentum and a reactive orbital momentum in terms of which we express the imaginary field momentum, whose transversal component produces an optical force on a magnetoelectric particle that, as we illustrate, may surpass and can be 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-
