I would expect that the Heisenberg equation of motion for the Dirac field would yield the Dirac equation. Indeed, these lecture notes claim it as a fact in eq 7.7 but without proof. My trouble is that I know the anti-commutation rules for the Dirac field but I don't know how to calculate the commutator with Hamiltonian, even if the Hamiltonian is expressed in terms of the field itself.
Can someone here provide some hints or tips?
Here is an old thread I started years ago on the same question.
