摘要:
Dirac bra and ket notation is developed for three‐dimensional space. A number of transformations, closure relations, and projection operators are discussed in some detail. The formal results are applied to examples pertaining to homogeneous isotropic and anisotropic systems, as well as to sums over photon polarization degrees of freedom. Most of the discussion is tailored for the student before his exposure to operator methods of quantum mechanics.
