What is it about?

Coherent electric field structures are commonly found in Earth's Magnetosphere. These are interpreted in theory as phase space holes. The potential associated with these electric fields traps electrons (if the potential has positive polarity) with suitable velocity and those with large velocity will pass through. Hence, this generates an equilibrium between the trapped and passing electrons. Such an equilibrium is called BGK equilibrium. In this paper, we study the effects of this wave potential on the generated equilibrium.

Why is it important?

This will be the only study that you will find where the effects of wave potential on the BGK equilibrium is addressed in detail. We answer some important questions like what is the effect of the width of the potential on the generated equilibrium? How does trapped density change with the change in the amplitude of the potential?


This kind of study is important for those who want to understand the BGK waves in detail. This is meant for the ones interested dig deep in a subject and try to be an expert in this area.
