Аннотация
© 2021 Elsevier LtdLongitudinal electrostatic baryon-acoustic waves have been studied systematically which can propagate in the uniform thermodynamically-nonequilibrium unmagnetized ambiplasma. The research was carried out in the frames of the linear theory and nonlinear theory according to the method of Sagdeev's pseudopotential. Two types of the periodic waves with in-phase (slow wave) and antiphase oscillations (fast wave) of protons and antiprotons were specified. The unknown before possibility of the existence of super-nonlinear waves in ambiplasma was shown for the first time. Fast and slow solitons were specified also. Wave profiles were calculated for all types of waves, they include flux profiles in the laboratory frame. Average proton and antiproton fluxes were calculated for the period of oscillations in the waves. It was shown that periodic trains of fast solitons could direct flows of protons and antiprotons in the opposite directions. This fact can be provided as a possible explanation of the baryon asymmetry of the modern Universe.
