The choice of the optimal approximation in the kinetic description of the vacuum creation of electron-positron plasma in strong laser fields
The paper justifies 2-similarity of kinetic equation solutions to describe vacuum emergence of electronpositron plasma under the effect of strong βlaserβ fields, where () is the intensity of the strong time-dependent βlaserβ field. The boundaries of existence of this similarity were studied
AlGaAs/GaAs Quantum Well Infrared Photodetectors
In this article, we present an overview of a focal plane array (FPA) with 640 Γ 512 pixels based on the AlGaAs quantum well infrared photodetector (QWIP). The physical principles of the QWIP operation and their parameters for the spectral range of 8β10Β ΞΌm have been discussed. The technology of the manufacturing FPA based on the QWIP structures with the pixels 384 Γ 288 and 640 Γ 512 has been demonstrated. The parameters of the manufactured 640 Γ 512 FPA with a step of 20Β ΞΌm have been given. At the operating temperature of 72Β K, the temperature resolution of QWIP focal plane arrays is less than 35 mK. The number of defective elements in the matrix does not exceed 0.5%. The stability and uniformity of the FPA have been demonstrated

Anti-Fermi-Pasta-Ulam energy recursion in diatomic lattices at low energy densities
We study the dynamics of one- and two-dimensional diatomic lattices with the interatomic Morse potentials for the initial conditions selected at the edge of the Brillouin zone of the dispersion spectrum, when only light atoms are excited with the staggered mode while all heavy atoms remain at rest (the so-called anti-Fermi-Pasta-Ulam problem). We demonstrate that modulational instability of such a nonlinear state may result in almost periodic temporal dynamics of the lattice with spatial localization and delocalization of energies. Such a recursion occurs many times with a very slow decay, especially for the initial states with low energy. The energy recursion results in the formation of highly localized, large-amplitude gap discrete breathers. For one-dimensional diatomic lattices, we describe the periodic energy recursion analytically for a simple model with the nearest-neighbor interaction and cubic anharmonicity
Comparison of Atmospheric Ionization for Solar Proton Events of the Last Three Solar Cycles
Numerical modeling of primary cosmic ray protonsβ transport through the Earthβs atmosphere was performed for the energy spectra of solar energetic particle events (SEPs). Several events in the last three solar cycles were considered. A comparative analysis of the characteristics of coronal mass ejections and primary proton fluxes was carried out. The main results were quantitative estimates of the calculated atmospheric ionization count rate for a wide range of altitudes (from sea level up to 98 km). The difference in the influence of solar protons on the Earthβs atmosphere is considered for seven SEPs divided into three groups with similar solar sources (X-flare magnitude and coordinates) but with different characteristics of accelerated particle fluxes. The data obtained in this work are very important for future studies of radio wave propagation, atmospheric chemistry and climate change
