R. Shankar has introduced major additions and updated key presentations in this second edition of Principles of Quantum Mechanics. New features of this innovative text include an entirely rewritten mathematical introduction, a discussion of Time-reversal invariance, and extensive coverage of a variety of path integrals and their applications. Additional highlights include:






- Clear, accessible treatment of underlying mathematics


- A review of Newtonian, Lagrangian, and Hamiltonian mechanics


- Student understanding of quantum theory is enhanced by separate treatment of mathematical theorems and physical postulates


- Unsurpassed coverage of path integrals and their relevance in contemporary physics





The requisite text for advanced undergraduate- and graduate-level students, Principles of Quantum Mechanics, Second Edition is fully referenced and is supported by many exercises and solutions. The book’s self-contained chapters also make it suitable for independent study as well as for courses in applied disciplines.
