Charge Order, Superconductivity, and a Global Phase Diagram of Doped Antiferromagnets
Charge Order, Superconductivity, and a Global Phase Diagram of Doped Antiferromagnets
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 $\mathrm{Sp}(2N)$ 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 …
