Homework Help: Excercise on distinguishable particles interacting with Hamiltonian

  1. Feb 11, 2013 #1
    Please, help me with this problem!

    Two distinguishable particles of spin 1/2 interact with Hamiltonian
    with A a positive constant. S1,z and S2,x are the operators related to the z-component of the spin of the first particle and to the x-component of the spin of the second particle, respectively.
    If at t=0 the system is in its simultaneous eigenket of S1,z for the eigenvalue h/4pi (ħ/2) and of S2,x for the eigenvalue h/4pi (ħ/2), FIND THE STATE OF THE SYSTEM AT THE TIME t

    Attempt of solution:
    Firstly, one should use the formulas for temporal evolution. Please, help me!

    Note that the problem in the attachment states that the initial state is an eigenket for S2,z rather than S2,x.
