After an insulating regime the pseudogap (PG) first rises and then falls off again with the system eventually becoming a conventional metal. In the PG regime, the Fermi surface is reduced to Fermi arcs (upper panel, the high-symmetry points are Γ = (0, 0), X  = (π, 0) and M  = (π, π)). Concomitantly, commensurate antiferromagnetic and incommensurate magnetic fluctuations are present, demonstrated by the momentum-dependent spin susceptibility (lower row). The shadings serve as a guide to the eye throughout the manuscript.
