The study of the generation of magnetic fields in models of the early universe with chirally disturbed anomalies and the study of tensor scalar ratios and spectral indices in cosmological models of slow-rolling inflation and the study of manifestations of superconducting cosmic (super) strings as sources of oscillating processes view of the Unru effect. Investigation of photon force functions (FSF) taking into account low-energy states of the nucleus and experimental studies of cross-sections of nuclear reactions in interaction with neutrons on neutron generators Research methods: use of nuclear-physical equipment complexes and models of nuclear reactions, and interaction of gamma quanta and neutrons . A set of programs for the study of astrophysical processes on the DUNE detector has been developed. The generation of magnetic fields in models of the early universe with chirally disturbed anomalies is considered. The algorithm for determining the Unru temperature in the case of particles with nonzero spin is generalized. The dependence of the Unru effect on time is investigated. Cosmic strings as sources of ultrahigh energy neutrinos are considered. Diffusion of the Black-Simons number in Abelian calibration theories. Analytical expressions for E1, E2 and M1 photon force functions were tested and confirmed taking into account the FSF amplification due to the effects of the nucleus structure (presence of low-energy states) and the presence of the amplification factor between the response function and FSF in excited nuclei.  Product Description popup.authors Bezshyyko Oleh A.
