Interplay between relativistic energy corrections and resonant excitations in x-ray multiphoton ionization dynamics of Xe atoms [PDF]
, 2017 In this paper, we theoretically study x-ray multiphoton ionization dynamics of heavy atoms taking into account relativistic and resonance effects. When an atom is exposed to an intense x-ray pulse generated by an x-ray free-electron laser (XFEL), it is ionized to a highly charged ion via a sequence of single-photon ionization and accompanying ...

Morphological stratification of clouds by atmospheric electric field in active and quiet sun period
Известия Томского политехнического университета: Инжиниринг георесурсов, 2016 Relevance of the research. In recent decade, regional and global climate has changed significantly due to human activities, which became comparable with natural processes. The electric field of atmosphere can serve as an indicator of anthropogenic impact,

The accuracy of semi-numerical reionization models in comparison with radiative transfer simulations [PDF]
, 2018 We have developed a modular semi-numerical code that computes the time and spatially dependent ionization of neutral hydrogen (HI), neutral (HeI) and singly ionized helium (HeII) in the intergalactic medium (IGM). The model accounts for recombinations and provides different descriptions for the photoionization rate that are used to calculate the ...

Ionizing Radiation in Smoothed Particle Hydrodynamics [PDF]
, 2000 A new method for the inclusion of ionizing radiation from uniform radiation fields into 3D Smoothed Particle Hydrodynamics (SPHI) simulations is presented. We calculate the optical depth for the Lyman continuum radiation from the source towards the SPHI particles by ray-tracing integration.

Efficient numerical algorithm for multi-level ionization of high-atomic-number gases [PDF]
arXiv, 2022 An efficient numerical algorithm for the laser driven multi-level ionization of high-atomic-number gases is proposed and implemented in an electromagnetic particle-in-cell code SPACE. The algorithm is based on analytical solutions to the system of differential equations describing ionization evolution. Using analytical solutions resolves the multiscale
