$\displaystyle H_{\rm total}$	$\displaystyle \equiv$	$\displaystyle H_S+H_{SB}+H_B$
	$\displaystyle =$	$\displaystyle \Omega a^{\dagger}a + \sum_Q\gamma_Q(a_Q a^{\dagger} +a_Q^{\dagger}a ) + \sum_Q \omega_Q a_Q^{\dagger} a_Q.$	(35)

Here, $V\equiv H_{SB}=\sum_{i=1,2}S_i \otimes B_i$ with $S_1=a^{\dagger}$ ,

, an $B_1= \sum_Q\gamma_Q a_Q$ , $B_2= \sum_Q\gamma_Q a_Q^{\dagger})$ . The indices

and

now do play a role.
