For n 1 ≠ n 2⁠, we have at z = 0 δ P 1 − e n 1 δ ϕ = δ P 2 − e n 2 δ ϕ ,(30)and hence δ P 1 − δ P 2 = e ( n 1 − n 2 ) δ ϕ . (31)Equations (27) and (31) show that δP is continuous at z = 0 for n1 = n2 and no electric field is generated—this result is consistent with the boundary condition for the pressure at the interface z = 0 in zero surface tension fluid. When n 1 ≠ n 2⁠, the KHI generated electron velocity flows lead to the electron accumulation or depletion at the interface z = 0.

Ion beam-driven instabilities in a collisionless space plasma with low β, i.e. low plasma and magnetic pressure ratio, are investigated using particle-in-cell (PIC) simulations. Specifically, the effects of different ion drift velocities on the development of Buneman and resonant electromagnetic (EM) right-handed (RH) ion beam instabilities are studied. Our simulations reveal that both instabilities can be driven when the ion beam drift exceeds the theoretical thresholds.
