Adiabatic theory of strong-field ionization

Date Mi, 29.08.2018 - Mi, 29.08.2018
Time 11:00
Speaker Dr. Oleg I. Tolstikhin, Moscow Institute of Physics and Technology
Location ETH Hönggerberg, HCI J243
Program Abstract:
The ratio of the electronic motion timescale in atoms and molecules (tens of attoseconds) to the characteristic time of variation of the electric field in strong infrared laser pulses (femtoseconds) provides a natural small parameter for solving the laser-matter interaction
problem using asymptotic methods. The adiabatic theory [Tolstikhin and Morishita, 86, 043417 (2012)] implements the asymptotic approach uniformly in the field amplitude. Namely, it yields analytical formulas for the solution of the time-dependent Schrödinger equation and strong-field ionization observables which become exact as the laser frequency tends to zero independently of the laser intensity. In my talk, I review basic elements of the adiabatic theory and discuss its recent applications in strong-field physics.
