Doping dependence of spin modes in the Normal State of the Two-Dimensional Hubbard Model

ORAL

Abstract

We compute spin susceptibilities in the 2D Hubbard model both at and away from half-filling for a range of correlation strengths. We use the combination of dynamical mean field theory and the dual fermion methodology to compute generalized two-particle correlated vertex functions from which we construct the spin susceiptiblity. We present results for undoped, electron and hole-doped cases and compare the results to other theoretical work and to experimental data on both insulating parent cuprates and doped materials.
