Entanglement of orbital angular momentum in non-sequential double ionization
Nature Communications, 2022 In strong field ionization, entanglement between an electron and an ion has been discussed previously. Here the authors explore orbital angular momentum entanglement between the electrons released in non-sequential double ionization.

Pulse length effects in long wavelength driven non-sequential double ionization
New Journal of Physics, 2023 We present a joint experimental and theoretical study of non-sequential double ionization (NSDI) in argon driven by a 3100 nm laser source. The correlated photoelectron momentum distribution (PMD) shows a strong dependence on the pulse duration, and the ...

Ionic-state-resolved electron–electron correlation in strong-field double ionization
Results in Physics, 2021 In this paper, we theoretically investigate the nonsequential double ionization (NSDI) process of Ne induced by 400 nm linearly polarized laser field with a intensity above the recollision threshold using the S-matrix theory.

Anticorrelation in nonsequential double ionization of helium
Physical Review A, 2021 We calculate the correlated two-electron momentum distributions for nonsequential double ionization of helium in a 400-nm laser pulse with a peak intensity of $6.5\ifmmode\times\else\texttimes\fi{}{10}^{14}$ $\mathrm{W}/{\mathrm{cm}}^{2}$, which is below the recollision threshold, by using the quantitative rescattering model in which the lowering of ...

Intensity dependence in nonsequential double ionization of helium
Optics Express, 2020 Using the quantitative rescattering model, we simulate the correlated two-electron momentum distributions for nonsequential double ionization of helium by 800 nm laser pulses at intensities in the range of (2 − 15) × 1014 W/cm2. The experimentally observed V-shaped structure at high intensities [Phys. Rev. Lett.

Frustrated double ionization of argon atoms in strong laser fields
Physical Review Research, 2020 We demonstrate kinematically complete measurements on frustrated double ionization of argon atoms in strong laser fields with a reaction microscope. We found that the electron trapping probability after strong-field double ionization is much higher than ...

Ellipticity dependence of anticorrelation in the nonsequential double ionization of Ar
Optics Express, 2022 Within the framework of the improved quantitative rescattering (QRS) model, we simulate the correlated two-electron momentum distributions (CMDs) for nonsequential double ionization (NSDI) of Ar by elliptically polarized laser pulses with a wavelength of 788 nm at an intensity of 0.7 × 1014 W/cm2 for the ellipticities ranging from 0 to 0.3.

Communications Physics, 2023 Nonsequential double/multiple ionization (NSDI/NSMI) of atoms in strong laser fields is a paradigm system for studying field-intervened electron-electron correlation. However, there exists a long-standing debated topic as to how NSDI/NSMI is triggered in

Nonsequential double ionization driven by inhomogeneous laser fields
Optics Express, 2022 With a three-dimensional classical ensemble method, we theoretically investigated the correlated electron dynamics in nonsequential double ionization (NSDI) driven by the spatially inhomogeneous fields. Our results show that NSDI in the spatially inhomogeneous fields is more efficient than that in the spatially homogeneous fields at the low laser ...

Nonsequential Double Ionization of Atoms in Strong Laser Pulses [PDF]
Acta Physica Polonica A, 2007 It is now possible to produce laser pulses with reproducible pulse shape and controlled carrier envelope phase. It is discussed how that can be explored in double ionisation studies. To this end we solve numerically the Schrodinger equation for a limited dimensionality model which nevertheless treats electron repulsion qualitatively correctly and ...
