Glossary of elementary quantum mechanics

This is a glossary for the terminology often encountered in undergraduate quantum mechanics courses.

Cautions:

  • Different authors may have different definitions for the same term.
  • The discussions are restricted to Schrödinger picture and non-relativistic quantum mechanics.
  • Notation:
    • - position eigenstate
    • - wave function of the state of the system
    • - total wave function of a system
    • - wave function of a system (maybe a particle)
    • - wave function of a particle in position representation, equal to
