Abstract

We analyze the nature of the single-particle excitations and the collective modes in the nonmagnetic phase of a generalized t-J model to next to leading order in 1/N. We discuss the essential features of the spectral function of the t-J model and we evaluate it numerically for values of the parameters t,J, and of the doping level relevant to the copper-oxide planes.
