We extend Berezinskii's diagram technique to study a one-dimensional disordered wire with Rashba and Dresselhaus spin-orbit interactions. By factorizing the retarded and advanced Green's functions in coordinate space, we transform the coordinate dependence of the functions to the impurity vertices. Our calculations show that the impurity vertices contributing to the correlators remain the same as in the conventional technique, except they are written in a 2 x 2 matrix form and the Fermi velocity now depends on the spin-orbit coupling constants. We use the diagrammatic method of Berezinskii with spin-orbit interaction to obtain the electron density distribution of the localized state p infinity(y).
We extend Berezinskii's diagram technique to the one-dimensional disordered wire containing Rashba and Dresselhaus spin-orbit interactions. The retarded and advanced Green's functions are factorized in coordinates space in the presence of spin-orbit interactions. This factorization allows us to transform all coordinate dependence of the Green's functions from lines to the impurity vertices. Our calculations show that all possible impurity vertices giving a contribution to the correlators do not differ from those given in the conventional technique, except that they are written in a 2 x 2 matrix form and the Fermi velocity r iota*F now depends on the spin-orbit coupling constants. The diagrammatic method of Berezinskii with spin-orbit interaction is used to obtain the distribution of the electron density of the localized state p infinity(y).
