Quantum Theory of Angular Momentum
@inproceedings{Mattis1981QuantumTO, title={Quantum Theory of Angular Momentum}, author={Daniel Charles Mattis}, year={1981} }
This chapter affords a brief summary of the quantum theory of angular momentum. As the angular momentum of a charged particle is proportional to its magnetization, this subject is at the core of the theory of magnetism. We shall show that motional angular momentum is inadequate, and introduce spin angular momentum. We shall develop operator techniques expressing angular momentum or spin operators in terms of more primitive fermion or boson operators. The topics of spin-one-half and spin-one are…

This paper demonstrates how to use the spin SU(2) and the point symmetries in optimization of the theoretical condensed matter tools: the exact diagonalization, the renormalization group approach, the cluster perturbation theory.
Gauged Laplacians on Quantum Hopf Bundles
