The development of optical frequency standards with a relative uncertainty of reproducing the time and frequency units at a level as low as 10−17–10−18 calls for an unprecedented accuracy in estimating the role of higher orders of optical nonli

Compact analytic expressions have been derived by a direct expansion in ħ → 0 for the nonrelativistic amplitude of Coulomb bremsstrahlung radiation (BR), the differential (in frequency and angles of the scattered electron) BR cross section, and th

The two-photon above-threshold ionization of atoms is calculated using numerical algorithms of the Pade approximation in the model-potential method with the Coulomb asymptotics. The total and differential cross sections of the above-threshold ionizat

A technique for calculating above-threshold bound-bound transitions of an atomic optical electron, based on the use of generalized Sturm expansion of the Green’s function for a potential with a Coulomb asymptotics has been developed within the mode

An ab initio parametrization of the doubly-differential cross section (DDCS) for two-photon double ionization (TPDI) from an s2 subshell of an atom in a 1S0-state is presented. Analysis of the elliptic dichroism (ED) effect in the DDCS for TPDI of He

Recent progress in optical lattice clocks requires unprecedented precision in controlling systematic uncertainties at $10^{-18}$ level. Tuning of nonlinear light shifts is shown to reduce lattice-induced clock shift for wide range of lattice intensit

It is shown that analytical results for amplitudes of two-photon transitions from an arbitrary bound state of the hydrogen atom published in two recent papers in this journal reduce to an essentially simpler form that considerably simplifies both ana

On the basis of the generalized Sturm expansion of the radial part of the Coulomb Green function, a computational method is proposed and numerical results are presented for the dynamic hyperpolarizability γ and the corrections E (4) (quadratic in th
