Paper Abstract

We predict that nanoparticles of octupolar symmetry (nano-triangles and nano-tetrahedra), whose orientation cannot be affected by means of linear optics, subjected to a coherent mixture of fundamental and second harmonic fields will rotate and orient controlled by the relative phase between these fields. This is due to the generation of the second-harmonic polarization and its interaction with the second-harmonic field. We have described this effect quantitatively for triangular and tetrahedral clusters of metal nanospheres where it can be observed experimentally and used in applications.
