Basic Representation Theory. vectors under rotations, or antisymmetric tensors under boosts). We begin by defining a representation of a group as a vector space on which that group acts, and we give many examples, using the vector spaces we met in Chap. . and the groups we met in Chap. .. We then discuss how to take tensor prdialect 发表于 2025-3-25 15:59:11
The Wigner–Eckart Theorem and Other Applicationsmatrices and Dirac bilinears. We begin by discussing the perennially confusing concepts of vector operators and spherical tensors, and then unify them using the notion of a representation operator. We then use this framework to derive a generalized selection rule, from which the various quantum-mech饶舌的人 发表于 2025-3-25 20:28:51

We conclude by showing that Dirac’s famous gamma matrices can be understood in terms of representation operators, which then immediately gives the transformation properties of the ‘Dirac bilinears’ of QED.Infuriate 发表于 2025-3-26 06:14:30
