comment Particle in a box under harmonic driving
Thanks, but I'm interested in exactly the non-perturbative limit, where the Rabi oscillation can happen.

comment Adjoint of momentum operator
The adjoin of the differential operator $\nabla^\dagger = -\nabla$ can be proved by integration by part.

comment What is mean by 'good quantum number' in spectroscopy?
If $[H,A]\neq0$ then the $A$ (e.g. angular momentum) is not good quantum number. This means if you have a state with specific energy, and you measure the angular momentum, you will get different values.
