Topics on Multiphoton Processes in Atoms

- P. Lambropoulos
- Chemistry
- 1976

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–bound… Expand

Optimal gauge and gauge invariance in non-perturbative time-dependent calculation of above-threshold ionization

- E. Cormier, P. Lambropoulos
- Physics
- 14 May 1996

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

- P. Lambropoulos, K. Papamihail, P. Decleva
- Physics
- 18 August 2011

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 rate… Expand

Correlated directional atomic clouds via four-heterowave mixing

- L. Buchmann, G. M. Nikolopoulos, O. Zobay, P. Lambropoulos
- Physics
- 16 March 2010

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 exhibit… Expand

Effect of the initial phase of the field in ionization by ultrashort laser pulses

- E. Cormier, P. Lambropoulos
- Physics
- 1 April 1998

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 angular… Expand

ac Stark shift of a two-photon transition induced by a model stochastic field

- J. Camparo, P. Lambropoulos
- Physics
- 1 December 1992

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 can… Expand

Above-threshold ionization spectrum of hydrogen using B-spline functions

- E. Cormier, P. Lambropoulos
- Physics
- 14 January 1997

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 a… Expand
