Superconducting and Antiferromagnetic Phases of Space-Time

Figure 2

Schematic illustration of the SC and AF phases of HTSC. For , the system favors AF alignment of neighboring spins. For SC emerges. The quasiparticles in the AF phase spin waves and in the SC phase they are “triplons,” dimers consisting of two neighboring spins which are aligned parallel to each other. In between the AF and SC phases there is a pseudogap phase which consists of a mixture of SC and AF phases.
