Optical conductivity of the Hubbard chain away from half filling

Optical conductivity of the Hubbard chain away from half filling

We consider the optical conductivity σ1(ω) in the metallic phase of the one-dimensional Hubbard model. Our results focus on the vicinity of half filling and the frequency regime around the optical gap in the Mott insulating phase. By means of a density-matrix renormalization group implementation of...
