%0 Journal Article %T Charge order, superconductivity, and a global phase diagram of doped antiferromagnets %A Matthias Vojta %A Subir Sachdev %J Physics %D 1999 %I arXiv %R 10.1103/PhysRevLett.83.3916 %X We investigate the interplay between lattice-symmetry breaking and superconducting order in a two-dimensional model of doped antiferromagnets, with long-range Coulomb interactions and Sp(2N) spin symmetry, in the large-N limit. Our results motivate the outline of a global phase diagram for the cuprate superconductors. We describe the quantum transitions between the phases, the evolution of their fermion excitation spectrum, and the experimental implications. %U http://arxiv.org/abs/cond-mat/9906104v2
