Seminar Title:

Light-matter interaction and optical forces mediated by surface guiding waves: the effects of spin-locking

Abstract:

In the focus of the talk, there will be the interaction of dipole sources with localized surface waves, such as guiding modes of dielectric nanofiber or plasmonic nanowire, as well as surface plasmon polaritons at the flat metallic interface. We will discuss how the spin-locking effect can change the picture of light-matter interaction and contribute in the generation of optical pulling forces. We see how optical binding of two nanoparticles can be stimulated through the generation of surface polaritons and nanofiber guiding modes.
