“Nodal Gap” Induced by the Incommensurate Diagonal Spin Density Modulation in Underdoped High- Superconductors

Figure 1

((a)-(b)) Intensity plots of the spectral function with and without the ID-SDW order, respectively. (c) The normal state Fermi surface. The arrow indicates the cut along which (a), (b), and (d) were taken. (d) The energy dependence of the spectral function along the arrow in (c) (from bottom to top).
