Plasma Physics: Debye Length

This lecture covers the rigorous definition of plasma, focusing on the Debye length and its significance in understanding plasma physics. It explains the concept of plasma as an ionized gas with collective effects, introduces the Debye length as a measure of screening in plasmas, and discusses the parameter space of plasmas. The lecture also delves into the Debye screened potential and the implications of deviation from quasi-neutrality in plasma physics.
