Ion-acoustic waves
Webarxiv.org WebIon Acoustic Waves. If we now take ion dynamics into account then the dispersion relation ( 8.23 ), for electrostatic plasma waves, generalizes to. (8.49) that is, we simply add an extra term for the ions that has an analogous form to the electron term. Let us search for a wave with a phase-velocity, , that is much less than the electron ...

WebWhen the liquid inside the cochlea moves, this movement bends the stereocilia, and this leads to the opening of ion channels (we will see this in the next part of the lecture). In turn, this will trigger a change in the membrane potential, which will ultimately result in the conversion of mechanical energy (the movement of the stereocilia) into a bioelectric … WebIon Acoustic The dispersion relation of an ion-acoustic wave propagating through a collisionless, unmagnetised plasma, having warm isothermal electrons and cold positive and negative ions has been derived. It is seen that the ion-acoustic wave will be unstable in the presence of streaming of ions.
