I'm not sure what is the correct interaction hamiltonian between an electron
in an atom and electromagnetic wave (described classically). According to
me there exist two version of this hamiltonian which differ by factor 2:
[tex]
H_{int} = \vec{E_0} \vec{r} \cos(\omega t)
[/tex]
or
[tex]
H_{int} = 2 \vec{E_0} \vec{r} \cos(\omega t) = \vec{E_0} \vec{r} \exp( \textrm{i} \omega t ) + \vec{E_0} \vec{r} \exp(- \textrm{i} \omega t )
[/tex].
Which one is correct?
