WebSimilarly, we can use matrices to represent the various spin operators. 10.1 SpinOperators We’ve been talking about three different spin observables for a spin-1/2 particle: the component of angular momentum along, respectively, the x, y, and zaxes. In quantum mechanics, there is an operator that corresponds to each observable. The WebTo determine the probability of finding the particle in a spin up state, we simply multiply the state of the particle by the adjoint of the eigenspinor matrix representing spin up, and square the result. Thus, the eigenspinor allows us to sample the part of the particle's state that is in the same direction as the eigenspinor.
