Influence of disorder on incoherent transport near the Mott transition
Influence of disorder on incoherent transport near the Mott transition
We calculate the optical and dc conductivity for half-filled disordered Hubbard model near the Mott metal-insulator transition. As in the clean case, large metallic resistivity is driven by a strong inelastic scattering, and Drude-like peak in the optical conductivity persists even at temperatures when the resistivity is well beyond the …
