THE DIRAC PICTURE
Now consider a Hamiltonian H = H0 + V , where the perturbation V may depend explicitly on time. We write the Schr¨odinger picture time evolution operator as
Rewrite the Schr¨odinger equation as an equation for W
VI (t) is the operator V , with each Schr¨odinger picture operator replaced by the corresponding Heisenberg picture operator evolved with the Hamiltonian H0. VI (t) is called the interaction picture version of the perturbation V and is time dependent even if the original perturbation is time independent. The results of the previous section tell us that
