Spin and Angular Momentum



In this chapter we put together everything we have studied so far—Mathematica, quantum mechanics, computational bases, units—to study simple quantum systems. We start our explorations of quantum mechanics with the description of angular momentum. The reason for this choice is that, in contrast to the mechanically more intuitive linear motion (Chap.  4), rotational motion is described with finite-dimensional Hilbert spaces and thus lends itself as a relatively simple starting point. As applications we look at the hyperfine structure of alkali atoms, lattice spin models, and quantum circuits.
