Non-sequential double ionization below laser-intensity threshold: Anticorrelation of electrons without excitation of parent ion
D. I. Bondar, G. L. Yudin, W. -K. Liu +2
Two-electron correlated spectra of non-sequential double ionization below laser-intensity threshold are known to exhibit back-to-back scattering of the electrons, viz., the anticor…
Adaptation of the Modified Adiabatic Approximation to Strong Field Ionization
Denys I. Bondar, Wing-Ki Liu, Gennady L. Yudin
Savichev's modified adiabatic approximation [Sov. Phys. JETP 73, 803 (1991)] is used to obtain a general form of a quantum-mechanical amplitude of ionization by a low-frequency las…
Unified ab initio treatment of attosecond photoionization and Compton scattering
G. L. Yudin, D. I. Bondar, S. Patchkovskii +2
We present a new theoretical approach to attosecond laser-assisted photo- and Compton ionization. Attosecond x-ray absorption and scattering are described by $\hat{\mathrsfs{S}}^{(…
Photoelectron spectra in strong-field ionization by a high frequency field
Denys I. Bondar, Michael Spanner, Wing-Ki Liu +1
We analyze atomic photoelectron momentum distributions induced by bichromatic and monochromatic laser fields within the strong field approximation (SFA), separable Coulomb-Volkov a…
