Self-sustaining sound in collisionless, high-β plasma
Using analytical theory and hybrid-kinetic numerical simulations, we demonstrate that, in a collisionless plasma, long-wavelength ion-acoustic waves (IAWs) with amplitudes 𝛿𝑛/𝑛0≳2/𝛽 (where 𝛽≫1 is the ratio of thermal to magnetic pressure) generate sufficient pressure anisotropy to destabilize the pl...
