Abstract:
We consider the interaction of metallic nanoparticles with electromagnetic fields carrying orbital angular momentum. The latter are known as "twisted photons". The ground-state and the dynamics of nanoparticles in such conditions is described in the framework of a non-linear Schrodinger equation derived within Density Functional Theory approximations. The density, current and multipolar responses of the system are computed for various spherical components of a twisted wave.
