$\displaystyle H_{\rm total}$	$\displaystyle \equiv$	$\displaystyle H_S+H_{SB}+H_B$
	$\displaystyle =$	$\displaystyle \Omega a^{\dagger}a + \sum_Q\gamma_Q(a_Q+a_Q^{\dagger})(a+a^{\dagger}) + \sum_Q \omega_Q a_Q^{\dagger} a_Q.$	(34)

Here, $V\equiv H_{SB}=S \otimes B$ with $S=a+a^{\dagger}$ and $B= \sum_Q\gamma_Q(a_Q+a_Q^{\dagger})$ . The indices

and

play no role here.
