thank you .. things become more clearer but i still have a question at the same plasma .. could i have both electron and ion waves (although we didn't treat the electrons adiabatically at studying the electron waves ) ??!

thanks for your comments ... :)

i study the electrostatic waves at plasma (as a beginner) and i come to some questions and hope to find a help 1) how could we ignore magnetic field (taking B =0) although we have oscillating charges (what particularly electrostatic wave means ) 2) at studying ion acoustic they always...

Hi friends in my class we had to study some topics out of our interest .. i tried for along time to understand them but the teacher's slides is not enough for understanding so i ask if anyone can give me sources to study the topics (the same way ) which attached as a photo note : i studied...

I read a paper and i can't understand how can we make the conversion (that attached in photo) i mean how i get formula (5) from previous one

i want second equation that ended by root of alpha starting by just following the sequence given at the photo that was mentioned here https://arxiv.org/pdf/1510.07813.pdf

Hello i read a quantum mechanics part and found a part of mathematics that i am not a familiar with it so i need a help how to get the equation at the bottom of the attached photo (the mathematics of applying variational method )

so happy that finally one put his hand on my confusion :)) at first i apologize as i am a beginner at his topic so my question may appear trivial you said ' with a fluid model, we can say the fluid is moving with velocity (vx, vy, vz) at point (x, y, z). But that doesn't mean every particle is...

mm i understood the difficulty at dealing with such high number of particles could i say that both kinetic and fluid model are both statistical approaches or what in fact the difference between both of them

hi ,, hello dears first i hope i choose the suitable section to put my question i want in fact to distinguish between different methods to model or study or describe plasma physics .. from my read i found that there are various ways to study plasma physics one way is the single particle...
