We employ dynamical mean-field theory to study the optical conductivity sΓ°oΓ of one hole in the Holstein-t-J model. We provide an exact solution for sΓ°oΓ in the limit of infinite connectivity. We apply our analysis to Nd 2Γx Ce x CuO 4 . We show that our model can explain many features of the optica
