The resistivity of alkali-metal halide solutions and the effects of '2k_F' scattering

Dynamical localisation of conduction electrons in one-dimensional disordered systems

“…On the other hand, the marginal distributions of the WDF in the momentum space show two maxima of the distribution of momentum placed around ± p 0 (where p 0 is the initial value of the momentum). It seems to be in agreement with the general theory of weak localisation because the multiple scattering processes due to the constructive quantum interference exhibit a narrow backscattered peak [5].…”

“…One of the main consequences of these correlations is the phase coherence of the carriers. This coherence enhances the classical return probability and leads to the correction to the diffusion process of conduction electrons [2][3][4][5] The phenomenon behind the correction is called the weak localisation and it is perceived as a precursor of the Anderson or strong localisation. The latter takes place in the limit of strong disorder when the coherent multiple scattering processes can block the electronic transport in the disordered environment.…”

Nonmetal-metal transition in metal–molten-salt solutions

“…4,8,10,18,27 The observed infrared dielectric anomaly 6 could indicate that the NM-M transition may occur at a metal concentration as low as xӍ0.1; however, this transition should really appear through a divergence of the static dielectric constant. 28 More probably 18 the anomaly simply indicates the appearance of sizable metallic clusters, the system as a whole still being in a nonmetallic state.…”

Quantum Kinetic Theory of the '2kF' Scattering Mechanism for Three-Dimensional Structurally Disordered Systems in the Ioffe-Regel limit

“…For τ FZ /τ = 1, the minimal value of the parameter k F is equal to 2.41 (not ≈ 1). It is an important result of the MH theory of the strong localisation, because the critical value of parameter k F determines the Anderson localisation at T = 0 K within the framework of the MH theory [11].…”
