Speaker: Oleg I. Tolstikhin, National Research Center “Kurchatov Institute”, Moscow, Russia Time: Thursday, November 3 at 10:15 Place: 1520-732 Title: Adiabatic theory of ionization of atoms by intense laser pulses Abstract: In the laser-atom interaction problem, the adiabatic approximation applies for sufficiently long wavelengths uniformly with respect to the amplitude of the laser field. A review of the first steps in the development of the adiabatic theory of ionization of atoms by intense laser pulses will be presented. The tunneling regime of the Keldysh theory and so-called `strong field approximation' are only a weak-field limit of the adiabatic theory.
