Introduction to quantum mechanics David Morin, morin@physics.harvard.edu This chapter gives a brief introduction to quantum mechanics. Quantum mechanics can be thought of roughly as the study of physics on very small length scales, although there are also certain macroscopic systems it directly applies to. The descriptor \quantum" arises
Quantum theory explains the nature and behavior of matter and energy on the atomic and subatomic level. Topics include Fundamental Concepts, Quantum Dynamics, Composite Systems, Symmetries in Quantum Mechanics, and Approximation Methods.
The three themes of quantum theory—the quantization of energy and the probabilistic behavior of energy quanta, the wave–particle nature of some matter, and Planck's constant—formed an interrelated set of ideas that lacked a universality and coherence necessary for them to constitute a scientific theory.
classical Hamiltonian theory can be transcribed into quantum mechanics by the simple rule, 1 {A,B}PB ⇒ [A,B]. (9) i~ where the quantum operatorsA and B arethe same functions ofthe operators xˆj and pˆj as Aand Bare of xj and pj. This remarkable rule tells us how to guess the quantum theory corre-sponding to a given classical dynamical system.
