Theoretical Physics Compact III

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 clearly illustrated in diagrams. The required mathematics is derived in a physical context and explained transparently. Contents: Principles of Classical Physics - Limits of Classical Physics - Beginnings of Quantum Theory: Matter Waves - Quantum Theory of a Particle - Operators and Expectation Values - Measurements and Probabilities - Particles under the Influence of External Forces - Fundamentals of Scattering Theory - The Hilbert Space - Operators in Hilbert Space - The Time Evolution Operator - Particle Number Representation for Fermions - Particle Number Representation for Bosons - Quantization of the Radiation Field: Photons - Formal Scattering Theory - The Hartree-Fock Approximation - Superconductivity in the BCS Model Target Audience: This book is especially suitable for Bachelor's students in their second or third year. Prerequisites: Mathematical prerequisites include knowledge of analysis, linear algebra, and complex function theory. The Author: Wolfgang Cassing is a retired Professor of Theoretical Physics at the Justus-Liebig-University Gießen. His expertise lies in phase space dynamics of classical and quantum many-body systems, which also features in his scholarly book "Transport Theories for Strongly-Interacting Systems". This textbook series Theoretical Physics Compact also includes Classical Mechanics, Electrodynamics, and Quantum Statistics and Thermodynamics.
