I have the Hamiltonian for an S=5/2 particle given by:(adsbygoogle = window.adsbygoogle || []).push({});

H= a.Sz + b.Sz^2 +c.Sx where Sz and Sx are the spins in z and x directions respectively. The resulting matrix is tridiagonal symmetric but I cant find the eigenvalues..Any idea how to diagonalise it.

N.B: a is a variable and must be kept as a in matrix whereas b and c can be assigned values.

Thanks guys.
