Optical properties of the Holstein-t-J model from dynamical mean-field theory

Abstract

We employ dynamical mean-field theory to study the optical conductivity $\sigma (\omega )$ of one hole in the Holstein-t-J model. We provide an exact solution for $\sigma (\omega )$ in the limit of infinite connectivity. We apply our analysis to Nd${}_{2-x}$Ce${}_x$CuO${}_4$. We show that our model can explain many features of the optical conductivity in this compounds in terms of magnetic/lattice polaron formation.
