Ion-Acoustic Wave Dynamics in a Two-Fluid Plasma
<|reference_start|>Ion-Acoustic Wave Dynamics in a Two-Fluid Plasma: Plasma is a medium containing free electrons and cations, where each particle group behaves as a conducting fluid with a single velocity and temperature in the presence of electromagnetic fields. The difference in roles electrons and ions play define the two-fluid description of plasma. This paper examines ion-acoustic waves generated by the particles in both hot and cold plasma using a collisionless "Euler-Poisson" (EP) system. Employing phase-space asymptotic analysis, we establish that for specific wave speeds, EP acquires homoclinic orbits at the steady-state equilibrium and consequently, traveling waves. Combining python and Wolfram Mathematica, we captured visualizations of such behavior in one spatial dimension.<|reference_end|>
