Principles of Quantum Mechanics

In this second edition of Principles of Quantum Mechanics, R. Shankar introduces major additions and updates. Newly added features include an entirely rewritten mathematical introduction, a discussion of Time-reversal invariance, and extensive coverage of a variety of path integrals and their applications in contemporary physics. A review of Newtonian, Lagrangian, and Hamiltonian mechanics is also included. Student understanding of quantum theory is enhanced by separate treatment of mathematical theorems and physical postulates. This text is written at an advanced undergraduate- and graduate-level level and is supported by many exercises and solutions.
