Figure 1

[(a) and (b)] The diagrams which contribute to the main order in the diagrammatic expansion of the conductivity-conductivity correlation function. Here, the solid lines stand for the impurity averaged retarded or advanced Green functions, the filled circles stand for the renormalized current vertices and the long wavy lines stand for the diffusion ladders. [(c) and (d)] Hikami boxes of two types and additional diagrams which determine renormalization in the main order in $1∕k_{F}l⪡1$. The dashed lines correspond to the disorder potential. (e) Diagrammatic equation for renormalized current vertex.Reuse & Permissions
