Correlation Functions for Single-Particle Problems

  • Wilhelm Brenig


An important field for the application of transport theories has always been electrical conduction in solids. Particularly simple, at least with respect to many-body effects, is the residual resistivity due to the scattering of electrons by impurities and imperfections. Normally this mechanism governs the conduction at low temperatures, where contributions from electron-phonon and electron-electron interactions are frozen out and one can describe the situation approximately by a single-particle Hamiltonian
$$\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{H} = {\sum {\bar h\omega } _\mu }c_\mu ^*{c_u}.$$
