Modern Quantum Mechanics

This authoritative, modern introduction to quantum mechanics includes discussions of fundamental topics and newer developments and employs a direct approach to quantum systems and provides an immediate introduction to quantum formalism. Problems are integrated throughout the text. In this Revised Edition, degenerate time-independent perturbation theory has been reworked, and two supplements have been added on adiabatic change and geometrical phase (Berry phase) and non-exponential decays, to take into account developments in quantum mechanics which have become prominent since the original edition
