S-d Hybridization and Anisotropy of the Optical Second Harmonic at Low Frequencies
Abstract
Recent experiments show that the anisotropy of the optical second harmonic (SHG) response from noble metal surfaces persists at frequencies below those associated with interband transitions and plasma resonances. It is proposed that for noble metals this anisotropy is a consequence of the hybridization between s- and d-orbitals. By taking advantage of a moment expansion and related path counting methods, the relative importance of the different contributions to SHG can be identified. To illustrate this result, the nonlinear polarizations are calculated using the recursion method. Second harmonic generation at low frequencies, Noble metal surfaces, Hybridization
