Topics on Multiphoton Processes in Atoms
Publisher Summary The theory of multiphoton processes can be developed in a semiclassical or fully quantum mechanical formalism. It is not possible to separate multiphoton ionization from bound–boundExpand

Optimal gauge and gauge invariance in non-perturbative time-dependent calculation of above-threshold ionization
We discuss the problem of the choice of the gauge in which to represent the electromagnetic field in the non-perturbative time-dependent study of the interaction of atoms with intense laser fields.Expand

Theory of multiple ionization of xenon under strong XUV radiation and the role of the giant resonance
We examine the conditions under which multiple ionization of xenon, under strong radiation of photon energy 93 eV and pulse duration 10 fs, leading up to Xe21 + can be observed. Through a set of rateExpand

Correlated directional atomic clouds via four-heterowave mixing
We investigate the coherence properties of pairs of counter-propagating atomic clouds, produced in superradiant Rayleigh scattering off atomic condensates. It is shown that these clouds exhibitExpand

Effect of the initial phase of the field in ionization by ultrashort laser pulses
Abstract:We report on observable new features related to ionization of atoms by laser pulses of only few cycles and some intensity. We show that for particular photo-electron energies, the angularExpand

ac Stark shift of a two-photon transition induced by a model stochastic field
We have investigated the ac Stark shift of a two-photon transition induced by a model stochastic field by using a Monte Carlo technique. The model field has a stochastic single mode, which canExpand

Above-threshold ionization spectrum of hydrogen using B-spline functions
We present a method for the accurate calculation of above-threshold ionization (ATI) spectra of single active electron systems. The technique involves the expansion of the radial wavefunction onto aExpand
