Focusing on applications relevant to modern physics, this text for advanced undergraduates and graduate students surveys variational principles, examining their relationship to dynamics and quantum theory. It stresses the history and theory of these concepts rather than their mechanics, providing many insights into the development of quantum mechanics. 1968 edition. Reprint of the Dover 1979 edition.
Quantum Theory by David Bohm This advanced undergraduate-level text presents the quantum theory in terms of qualitative and imaginative concepts, followed by specific applications worked out in mathematical detail.
Introduction to the Quantum Theory: Third Edition by David Park Geared toward upper-level undergraduates and graduate students, this self-contained first course in quantum mechanics covers basic theory and selected applications and includes numerous problems of varying difficulty. 1992 edition.
Primer of Quantum Mechanics by Marvin Chester Introductory text examines classical quantum bead on a track: state and representations; operator eigenvalues; harmonic oscillator and bound bead in a symmetric force field; bead in spherical shell. 1992 edition.
