Sufficiently disordered metals display systematic deviations from the behavior predicted by semi-classical Boltzmann transport theory. Here the scattering events from impurities or thermal excitations can no longer be considered as additive-independent processes, as asserted by Matthiessen’s rule following from this picture. In the intermediate region between the regime of good conduction and that of insulation, one typically finds a change of sign of the temperature coefficient of resistivity…

Planckian dissipation and scale invariance in a quantum-critical disordered pnictide
Quantum-mechanical fluctuations between competing phases at $T=0$ induce exotic finite-temperature collective excitations that are not described by the standard Landau Fermi liquid framework. These
Displaced Drude peak and bad metal from the interaction with slow fluctuations.
Scattering by slowly fluctuating degrees of freedom can cause a transient localization of the current-carrying electrons in metals, driving the system away from normal metallic behavior. We
Optical investigations of the (dis)continuous metal-insulator transitions in strongly-coupled electron-lattice systems.
TLDR
It is conjecture that the manifestation of anomalous electronic transport properties and Mooij correlations near the MIT or superconductor-insulator transition in systems with non-negligible electron-lattice coupling effects may be linked to the coexistence of competing polaronic phases and the dynamical intertwining of the deformable lattice and the random electronic potential.
Tailoring thermal properties of functional materials
Thermal conductivity (κ) plays an essential role in functional devices. In some cases, high value is required to transfer heat efficiently. In others, low κ assists in maintaining a temperature
Anomalous electrical conduction and negative temperature coefficient of resistance in nanostructured gold resistive switching films
TLDR
The authors' data indicates that space charge limited conduction and Coulomb blockade are at the origin of the anomalous electrical behavior and the high density of extended defects and grain boundaries causes the localization of conduction electrons over the entire investigated temperature range.

The absence of resistivity saturation in many strongly correlated metals, including the high-temperature superconductors, is critically examined from the viewpoint of optical conductivity

Bad-Metal Behavior Reveals Mott Quantum Criticality in Doped Hubbard Models.
TLDR
It is shown that for the doped Mott insulator regime, the coexistence dome and the associated first-order Mott metal-insulator transition are confined to extremely low temperatures, while clear signatures of Mott quantum criticality emerge across much of the phase diagram.

TLDR
An intermediate "bad insulator" transport regime is identified which displays resistivity values exceeding the Mott-Ioffe-Regel limit and with a negative temperature coefficient, as often observed in strongly disordered metals.

TLDR
Results of a numerical analysis based on localization indicate that there is a unique and monotonic correlation between ..cap alpha… and rho for a specific disordered metallic system, in accord with the essential features of the new Mooij (..cap alpha.. vs rho) plot.

TLDR
A metal-insulator transition on increasing annealing temperature for a group of crystalline phase-change materials, where the metal- insulator transition is due to strong disorder usually associated only with amorphous solids, might enable multilevel resistance states in upcoming storage devices.
