Seminar Program

July 5 (Thr) 14:30- 17:00 ' Laser-atom/molecule interactions & Photon creation'
Place: Bldg. East 6, Rm. 803

Chair : T. Morishita
14:30-14:50
SPEAKER: Hsumin Huang, UEC
TITLE: Two-photon break up of collinear Coulomb three-body systems by ultrashort intense laser pulses
ABSTRACT:
We theoretically study two-photon break up dynamics of collinear Coulomb three-body systems interacting with ultrashort intense laser pulses. Here both nonlinear light-matter interactions and particle correlations play important roles. By analyzing the break up momentum distributions for various systems which have different mass ratios such as H-, H2+ and Ps-, we identify sequential and no-sequential process and found that different kinds of break up dominates in different systems.

14:50-15:30
SPEAKER: Erik Loetstedt, RIKEN
TITLE: Triple Compton effect: A photon splitting into three after collision with a free electron.
ABSTRACT:
The process in which a photon inelastically scatters off a free electron is called Compton scattering, and is well known. Perhaps less familiar are the higher-order Compton processes, where the incoming photon is split into two or more photons. Some recent results on the triple Compton effect, with three photons in the final state, will be presented. Of particular interest is that the polarizations of the three final photons are quantum mechanically correlated.

15:30-15:40 Break
15:40-16:20
SPEAKER: Takeshi Sato, University of Tokyo
TITLE: Multiconfigurational wavefunction approaches to electron dynamics in intense laser fields
ABSTRACT:
We are developing flexible time-dependent multiconfigurational wavefunction methods for correlated electron dynamics in intense laser fields.
In this talk, I will discuss on the generalized valence-bond (GVB) as a simplest possible wavefunction for describing intense-field ionizations.
Numerical applications of GVB and related techniques to 1-D models will be presented. 
Theoretical framework in multi-electron (beyond-two) systems will be briefly discussed.

16:20-17:00
SPEAKER: Oleg I. Tolstikhin, National Research Center "Kurchatov Institute" & Moscow Institute of Physics and Technology, Moscow, Russia
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 Keldysh theory and so-called strong field approximation is only a weak-field limit of the adiabatic theory.
17:00-
Free discussion, Rm 529

July 9 (Mon) 14:40- 15:40 'Tutorial talk'
Place: Bldg. East 6, Rm. 803

Chair : T. Morishita

SPEAKER: Oleg I. Tolstikhin, National Research Center "Kurchatov Institute" & Moscow Institute of Physics and Technology, Moscow, Russia
TITLE: Retardation in electrodynamics and adiabatic theory.
ABSTRACT:
We all know what is the retardation in electrodynamics. The development of the adiabatic theory of ionization of atoms by intense laser pulses has revealed a similar (but not identical) phenomenon. I will try to explain the similarity and differences.
