This graduate-level text's coverage includes the quantum theory of partial coherence and the nature of the relations between classical and quantum theories of coherence. Topics include partially coherent light, photoelectric counting distributions, dynamical determination of statistical description, and equations of motion and coherent-state representation of the electromagnetic field. 1968 edition.
The book explores innovative treatments of quantum problems through enhanced quantization procedures, linking classical and quantum theories. It begins with classical mechanics and progresses through Hilbert space, quantum mechanics, and scalar quantum field theory. Subsequent chapters refine analytical skills, examine specific models, and address perturbations. The concluding chapter summarizes findings and presents a conjecture on interacting covariant scalar quantum field theories. Symmetry serves as a key tool throughout, complemented by challenging exercises and comprehensive references.
