Collective Phenomena in Plasmas and Elsewhere presents an overview of the theoretical bases of these kinetic and hydrodynamic approaches, but also discusses their limitations, the links between them and their extension to quantum mechanics and relativity.
These methods were born in part out of the study of plasmas, but they also have more universal applications. A general framework for these approaches is outlined, followed by some applications in plasmas, gravitation, Bose–Einstein condensates and dark matter. Particular emphasis is placed on the analogies that can be made between all these different systems.
Kamel Ourabah is Associate Professor at the University of Science and Technology – Houari Boumediene, Algeria. His research interests focus on statistical physics and its applications in plasmas, gravitation and cosmology.
