Objetivo
The considerable progress achieved in the development of compact terawatt laser sources has led to intense theoretical and experimental investigations of the interaction of ultrashort, relativistically strong pulses with plasmas. The EM radiation of astrophysical objects, nuclei of galaxies, radiogalaxies, quasars, pulsars, may serve as a source of super strong fields in space. A whole set of non-linear effects which may occur in a plasma interacting with super strong EM radiation has been studied and already confirmed by experiments, but still the dynamics of various interesting phenomena have yet to be investigated in detail.
The principal OBJECTIVE of this project is to study systematically the spatio-temporal dynamics of relativistically intense short pulses both in laboratory and space plasmas. The formation of an ion-channel behind the pulse and wake-field generation in the self-guiding regime of relativistically intense asymmetric pulses; the quasistationary magnetic field, low-frequency EM wave generation and efficiency of these processes depending on the spatio-temporal profiles of superstrong EM pulses; the electron-positron and neutrino-antineutrino pair production; the dynamics of nonequilibrium neutrino gases and relativistically hot e-p plasmas embedded in ultrastrong EM fields are of particular interest.
The RESEARCH ACTIVITIES will include a thorough consideration of various nonlinear phenomena existing in both laboratory and space plasmas, and neutrino gases embedded in the fields of superstrong EM radiation. The theoretical investigations will be based on the hydrodynamic approach; although we aim to develop a kinetic theory, when it proves necessary. Corresponding numerical simulation studies shall be carried out to analyse the obtained theoretical results. Special attention will be focused on a comparison of the project results with observational information in cosmic and laboratory plasmas.
The EXPECTED RESULTS will provide new and useful knowledge about the self-guiding and self-channelling of superstrong EM radiation, QSM magnetic and LF EM field generation mechanisms, pair production, neutrino gas and hot e-p plasma dynamics in ultra intense fields, and will help to understand and clarify some yet unsolved problems of plasma-wave interaction theory. The outcome of these research activities will be of significant importance and may be used for planning future experiments.
