I've taken course on Quantum Mechnics, and understand some basics of

Now I have several questions:

1, I got the notion that an atom absorbs energy by pieces and only
having exactly the same energy can be absorbed. But I see in atom-
interactions monochromatic electromagnetic waves with nonzero
detuning can pump electrons to higher energy levels with certain
Is that notion not correct or other energy(so processes) involved in
the absorption?

2, How is energy conservation elucidated in quantum physics
complications such as quantization, probability?

3, How are hamiltonian operators constructed and proven right? Can the
form of
hamiltonian be recognized as part of postulates?

4, Is there a widely accepted quantization program of electromagnetic
field? Can
you recommend some readings about that?

5, How are multiphoton processes explained theoretically? Any book
deals with
this at length? Multiphoton processes are obviously different from one
absorption, what's the necessary conditions for its happening?

Thanks for your reading!
