Revivification of the Concept of Coexisting CDDW and DSC Orders for Bi2212
The Chiral d-density wave (CDDW or d+id) order, corresponding to the anti-ferromagnetic wave vector Q= (± (1− φ), ±φ),(±φ, ±(1−φ)) with φ ~ 0.2258 located roughly on the boundary of the Fermi pockets in the momentum space. is assumed to represent
