This book on theoretical plasma physics provides a solid introduction to the essential concepts and theories of the field. It covers both fundamental and advanced topics such as equilibrium and non-equilibrium statistics as well as the nonlinear description of a classical plasma. With detailed chapters on single-particle motion, kinetic theory, and macroscopic descriptions, the book offers a deep understanding of the physical processes in a plasma. It is aimed at students, researchers, and professionals seeking a precise and comprehensive presentation of the methods and solution strategies for current plasma problems. The book delivers a clear and structured presentation of classical plasma physics. It addresses current issues in fusion physics, laser plasmas, and the emerging field of complex plasmas. It serves as a reliable reference for scientific studies and practical applications. In this second edition, the book has been thoroughly revised and updated.
