Double occupancy (\(\left\langle {n_ \uparrow n_ \downarrow } \right\rangle\), upper panel) and ratio of local charge and spin susceptibility (χ ch /χ sz , lower panel) as function of the electron–phonon coupling strength g. Circles are obtained from the auxiliary impurity model of the Dual Boson simulations at T = 464 K, diamonds at T = 2321 K. Dashed green lines represent data for purely local interaction U; solid gray lines corresponds to the non-interacting limit
