Thanks for the reply.
It is not homework, but exam revision. Is that ok in this part of the forums?
I think maybe i did not correctly explain the problem?
We proved orthonormality for the eigenstates of the hamiltonian when assuming H is real and then the lecturer said that we would...
Hi,
I know how to prove the orthonormality of the hamiltonian when it is real but am struggling to work out how to prove it when the hamiltonian is not real.
When proving for a real hamiltonian the lefthand side equals zero as H(mn)=H(nm)complexconjugate. but if the hamiltonian is not...
