Effect of the finite speed of light in ionization of extended systems
I. A. Ivanov, Anatoli S. Kheifets, Kyung Taec Kim
We study propagation effects due to the finite speed of light in ionization of extended systems. We present a general quantitative theory of these effects and show under which cond…
Simple man model in the Heisenberg picture
I. A. Ivanov, Kyung Taec Kim
We describe an approximate solution to the Heisenberg operator equations of motion for an atom in a laser field. The solution is based on a quantum generalization of the physical p…
Entropy-based view of the strong field ionization process
I. A. Ivanov, Chang Hee Nam, Kyung Taec Kim
We apply information theoretic entropies of coordinate and velocity distributions in quantum mechanics for the description of the strong field ionization process. The approach is b…
Instantaneous ionization rate as a functional derivative
I. A. Ivanov, C. Hofmann, L. Ortmann +3
We describe an approach defining instantaneous ionization rate (IIR) as a functional derivative of the total ionization probability. The definition is based on physical quantities…
Comparison of RABITT and FROG measurements in the temporal characterization of attosecond pulse trains
Kyung Taec Kim, Kyung Sik Kang, Mi Na Park +3
The attosecond high harmonic pulses obtained from a long Ar-filled gas cell were characterized by two techniques - the reconstruction of attosecond beating by interference of two-p…
