Superconducting and Antiferromagnetic Phases of Space-Time

Figure 1

Simplified doping-dependent phase diagram of cuprate superconductors for both electron () and hole () doping. The phases shown are the antiferromagnetic (AF) phase close to zero doping, the superconducting phase around optimal doping, and the pseudogap phase. Doping ranges possible for some common compounds are also shown, after [26].
