Homework Statement
I see in chapters on perturbation theory and time-dependent variation, the Hamiltonian (usually expressed as H) is now printed as H(t). This is still the same Hamiltonian, correct? I assume this notation simply helps to signify that the total energy varies with time? If so, wouldn't the formal (and seemingly more revealing) expression be H(r,t)?
Similarly, in some instances, the hamiltonian is expressed as H(r). I assume this is to explicitly indicate that the total energy is a function of position.
