Abstract

How are the properties of a metal changed by strong inelastic scattering? We investigate this question within the two-dimensional [Formula presented] model using extended dynamical mean field theory and a generalized noncrossing approximation. Short-ranged antiferromagnetic fluctuations lead to a strongly incoherent single particle dynamics, large entropy, and resistance. Close to the Mott transition at low hole doping a pseudogap opens, accompanied by a drop in resistivity and an increase in the Hall constant for both lower temperatures [Formula presented] and doping levels. The behavior obtained bears surprising similarity to properties of the cuprates.
