Field Magnetic Magnetic field Measurment Uniform Uniform magnetic field

In summary, any pure state of spin-1/2 particle can be represented by a superposition of spin up and spin-down relative to an arbitrarily direction. However, if there is no magnetic field, the measurement of the spin is random and the system has a 50-50 chance to be in the spin-up or spin-down state along that direction. If there is a magnetic field and the particle enters it, a time evolution operator will act on it. The time evolution unitary operator is a function of the Hamiltonian which is a function of B and S. This means that the state should collapse into the one with the eigenvalue after that interaction. However, the time dependent state is still a superposition of the two base vectors lw
