Emergence of a Novel Pseudogap Metallic State in a Disordered 2D Mott Insulator
Emergence of a Novel Pseudogap Metallic State in a Disordered 2D Mott Insulator
It is well established that for non-interacting electrons, increasing disorder drives a metal into a gapless localized Anderson insulator. While in three dimensions a threshold in disorder must be crossed for the transition, in two dimensions and lower, the smallest amount of disorder destabilizes the metal. The nature of the …
