The static local charge susceptibility χcharge, and local charge fluctuation 〈ΔN2〉. (a) χcharge and (b) 〈ΔN2〉 is computed for V2O3 (orange diamonds) and Sr2RuO4 (blue circles). In the Hund system Sr2RuO4 both χcharge and 〈ΔN2〉 are large and only weakly dependent on temperature. By contrast, in the Mott system V2O3 they are much smaller and strongly temperature dependent. The orange arrows indicate that in V2O3 the minima of the local charge susceptibility and fluctuation occur at the same temperature scale, TM, as that marking the emergence of the quasiparticle peak in the local PDOS
