摘要:

Localized quantum wave packets can be produced in a variety of physical systems and are the subject of much current research in atomic, molecular, chemical, and condensed‐matter physics. They are particularly well suited for studying the classical limit of a quantum‐mechanical system. The motion of a localized quantum wave packet initially follows the corresponding classical motion. However, in most cases the quantum wave packet spreads and undergoes a series of collapses and revivals. We present a generic treatment of wave‐packet evolution, and we provide conditions under which various types of revivals occur in ideal form. The discussion is at a level appropriate for an advanced undergraduate or first‐year graduate course in quantum mechanics. Explicit examples of different types of revival structure are provided, and physical applications are discussed.
