Basic Concepts of Quantum Mechanics -- Representation Theory -- Approximation Methods -- Scattering Theory -- Fundamentals of Thermodynamics -- Quantum States and Temperature -- Microstate Probabilities and Entropy -- The Ideal Monatomic Gas -- Applications of Classical Thermodynamics -- Thermodynamic Potentials and Derivatives -- Matter Transfer and Phase Diagrams -- Fermi–Dirac and Bose–Einstein Statistics-- Quantum Mechanics and Low-Temperature Thermodynamics of Many-Particle Systems -- Second Quantization -- Gas of Interacting Electrons-- Superconductivity -- The Classical Theory of Fields -- General Relativity -- Relativistic Quantum Mechanics -- Gauge Theories of Quark and Lepton Interactions.

This book is a comprehensive account of five extended modules covering the key branches of twentieth-century theoretical physics, taught by the author over a period of three decades to students on bachelor and master university degree courses in both physics and theoretical physics.

The modules cover nonrelativistic quantum mechanics, thermal and statistical physics, many-body theory, classical field theory (including special relativity and electromagnetism), and, finally, relativistic quantum mechanics and gauge theories of quark and lepton interactions, all presented in a single, self-contained volume.
