This book, together with the three other volumes, offers a clear and comprehensive approach to theoretical physics for the entire Bachelor's program. Highlights: Theoretical derivations are linked with characteristic examples, their solutions, typical applications, and are clearly illustrated in figures. The required mathematics is derived within a physical context and transparently explained. Contents: Statistical Ensembles â Identical Particles â Concept of the Statistical Ensemble â Statistical Definition of Entropy â Statistical Ensembles in Equilibrium â Independent Identical Particles â Statistical Mechanics and Thermodynamics â Small Deviations from Equilibrium â The Ideal Fermi Gas â The Ideal Bose Gas â Real Gases â Magnetic and Electric Properties of Matter â Kinetic Theories Target Audience: This book is particularly suitable for Bachelorâs students in their final year. Prerequisites: Mathematical prerequisites include knowledge in calculus, linear algebra, and complex analysis. The Author: Wolfgang Cassing is a retired Professor of Theoretical Physics at the Justus-Liebig-University GieÃen. His expertise lies in the phase-space dynamics of classical and quantum many-body systems, which he incorporated into his textbook "Transport Theories for Strongly-Interacting Systems". His current textbook series Theoretical Physics Compact also includes Classical Mechanics, Electrodynamics, and Quantum Mechanics.
