If my view is correct, the universe may have a kind of domain structure. In one part of the universe, you may have one preferred direction of the axis; in another part, the direction of axis may be different.        ------Yoichiro Nambu (2008Nobel Prize)

The global phase-diagram of doped Mott insulators is splitted into two main regions by the RVB Temperature scale  . Our theory mainly focuses on the region below the temperature scale.
 
1, AF: Anti-ferromagnetic Phase. This region keeps Anti-ferromagnetic Long-range order (AFLRO).
2, SC: Super-conducting phase. This region keeps Off-diagonal Long-range order (ODLRO). The so-called "holon" field is condensed as a superfluid.
3, LPP (SVP): Lower Pseudo-gap Phase (Spontaneous Vortex Phase). In this phase, vortices randomly increase and move as the temperature is increased. The phase coherence of holon-condensate is killed gradually. experiments: Nernst effect.
4, UPP: Upper Pseudo-gap Phase. The crossover from strange-metal phase to SVP. (I am not clear about this phase)
5, SG: cluster Spin-glass phase. This phase is a disorder phase which is not dominant.
