We develop a new method based on the continuous-fraction approach as applied to the electrostatic boundary problem for determining surface plasmon resonances of coupled nanospheres. The resonance frequency dependence on interparticle gap (plasmon nan

An approximate analytical approach is developed for the calculation of the surface plasmon frequency of a system of interacting nanospheres for arbitrary values of interparticle distances. In addition to having a simple and physically clear form, the

Semi-analytical method of surface plasmon frequency calculation for the system of two almost touching coupled dielectric coated metallic nanospheres is presented. The method allows transforming the problem to numerical solution of two simple algebrai

In this paper, we calculate the two-photon ionization (TPI) cross-section for pump-probe scheme in Ag neutral cluster. The pump photon energy is assumed to be close to the surface plasmon (SP) energy of cluster in dielectric media. Due to this choice

The input intensity dependence of bulk InGaAsP sample transmission at different wavelengths around 1500 nm and intensities between about 0.2 and 120 MW/cm 2 is measured. Saturation of the interband absorption is observed. A theory of nonlinear absorp

Under certain conditions of the incident light polarization direction a Fano resonance arises in small gold nanorods arranged in a H-like configuration. This stems from the coupling between a bright dipole plasmon mode excited in the horizontal rod a

The interaction of vibrational modes in ultrathin metallic films through anharmonicity is investigated. It is shown that under specific relations between vibrational frequencies the enhancement and coupling of certain modes during their excitation ar

We consider the problem of surface plasmon (SP) oscillations in a pair of coupled spherical metallic nanoparticles (MNP) analytically and compare the results with those obtained experimentally as well as by numerical methods: discrete dipole approxim
