WebWe develop a full microscopic replica field theory of the dynamical transition in glasses. By studying the soft modes that appear at the dynamical temperature, we obtain an effective theory for the critical fluctuations. This analysis leads to WebB. Hypernetted chain scheme We compute the ion pair-correlations in the PM de- scribed in the previous section, by numerically solving the OZ equations [9] in combination with the approxi- mate HNC closure [10–12]. In an isotropic, homogeneous 3 ﬂuid mixture, the coupled OZ equations may be written as γij(x) = χk Z ddx′c ik(x ′)[c
