Shake-Off Process in Non-Sequential Single-Photon Double Ionization of Closed-Shell Atomic Targets
Atoms, 2022 Amusia and Kheifets in 1984 introduced a Green’s function formalism to describe the effect of many-electron correlation on the ionization spectra of atoms. Here, we exploit this formalism to model the shake-off (SO) process, leading to the non-sequential

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.

Frontiers in Physics, 2023 With the three-dimensional semi-classical ensemble model, we studied the non-sequential double ionization by orthogonal two-color laser pulses. Our calculations show that the proportion of events experiencing multiple returnings, the sum of the final ...

Saturating multiple ionization in intense mid-infrared laser fields
New Journal of Physics, 2021 The interpretation of experimental data from novel mid-infrared few-cycle laser sources requires an understanding of ionization mechanisms and knowledge about related ion yields.

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 ...

Controlling electron recollision with combined linear and circular polarization
Frontiers in Physics, 2022 We theoretically investigate the non-sequential double ionization of Ar atoms in the combined fields of linearly polarized laser and circularly polarized laser through 3D semiclassical simulations. By partially overlapping the two time-delayed multicycle

First discovery of two polyketide synthase genes for mitorubrinic acid and mitorubrinol yellow pigment biosynthesis and implications in virulence of Penicillium marneffei. [PDF]
PLoS Neglected Tropical Diseases, 2012 BACKGROUND:The genome of P. marneffei, the most important thermal dimorphic fungus causing respiratory, skin and systemic mycosis in China and Southeast Asia, possesses 23 polyketide synthase (PKS) genes and 2 polyketide synthase nonribosomal peptide ...

Attosecond streaking using a rescattered electron in an intense laser field
Scientific Reports, 2020 When an atom or molecule is exposed to a strong laser field, an electron can tunnel out from the parent ion and moves along a specific trajectory. This ultrafast electron motion is sensitive to a variation of the laser field.

Non-sequential double ionization with near-single cycle laser pulses
Scientific Reports, 2017 A three-dimensional semiclassical model is used to study double ionization of Ar when driven by a near-infrared and near-single-cycle laser pulse for intensities ranging from 0.85 × 1014 W/cm2 to 5 × 1014 W/cm2. Asymmetry parameters, distributions of the
