1. The problem statement, all variables and given/known data The Hamiltonian for an individual anti-ferromagnetic dimer is given as H=J S(1) dot S(2) -μB(Sz(1)+Sz(2)) Where J and μ are positive constants. Find the eigenvalues and Eigenvectors of H 2. Relevant equations 3. The attempt at a solution Haven't attempted anything really, I have no idea how to convert that equation into a matrix that I can take the eigenvalues of. I can take the dot product of S(1) and S(2), but I don't see how that gets me anywhere. Any hints?
