Abstract

The proposed work presents a model to understand the lower hybrid turbulence in the magnetic reconnection regions of magnetopause by the energetic electron beams (generated by the magnetic reconnection process). The magnetic reconnection process has been substituted by the energetic electron beam source in this model. Due to beam energy, lower hybrid waves (LHW) evolve from very small to large amplitude (saturation) and then to LHW localization and the turbulent state. A nonlinear two-dimensional model with the help of two-fluid dynamics has been developed. The mathematical model considers the interaction between pump LHW and low frequency magnetosonic wave (MSW). The MSW, present in the background, has been contemplated as the source of density perturbations in LHW dynamics. The ponderomotive force components arise due to high-frequency LHW. With the help of the growth term associated with the electron beam, dynamical equations for LHW and MSW have been derived. The two coupled equations, thus obtained, are solved with the help of numerical simulation techniques. The results show the LHW’s temporal evolution (growth) from a very small amplitude and then the formation of localized structures and turbulence.
