I am a Ph.D. student in theoretical physics. I'm working on Plasma Physics and have a Master's degree in Quantum Information. I hope I can benefit from this excellent platform.
It is usual, in plasma physics, to combine the kinetic description for electron fluid and the hydrodynamic description for ion fluid, when studying the plasma properties or the dynamics of the electrostatic waves.
I am wondering what are the physical meaning and limits of such an approach.
Thanks.
