(2.1) (20 points) A spin 1/2 particle is in an eigenstate of Sy with eigenvalue h/2 at the initial time t = 0. At that time, it is placed in a magnetic induction B = B2, and it is then allowed to precess in that induction for the time T. Then, at that instant T, B is instantaneously rotated from the z to the y direction, becoming B = Bį. After another identical time interval T occurs, a measurement of...

We’re going to work out some things about the algebra of a spin-1 particle. First, note that there are three eigenstates of Sz for the spin one particle, with eigenvalues 0,±h̄. Let’s denote the orthonormal basis states |+ 1〉, |0〉, and |− 1〉, with eigenvalues +h̄, 0, and −h̄ respectively. a What are the values of the below expressions? Sz|+1〉 = Sz|0〉 = Sz|−1〉 =
