Diffusive quantum transport
Based on the discussion of electron interference in Chapter 14, this chapter returns to electronic transport in large diffusive systems. It discusses the weak localization effect, i.e., quantum corrections to the Drude conductivity that are based on phase-coherent backscattering of electrons, and the suppression of these effects at finite magnetic fields. It gives an outline of the basic ideas behind the scaling theory of localization and its relation to the weak localization correction is made transparent. It then discusses the weak anti-localization, which requires revisiting spin-orbit interaction effects and spin-interference.
