40. Y. Nagai (in preparation). We set U q t r s = 0.46 U q t, M r s regarded as the nearly critical parameter under the RPA scheme in normal states of this system.
41. ′′ (E) within L < 1 / 2, which we cannot discriminate from Q ∼ (1 / 2 1 / 2 0) experimentally because of a small Q-value difference owing to the long c-axis length than that of a axis.
42. There is also a possibility of a pocket-like node on electron FS as is discussed recently [I. I. Mazin, Phys. Rev. B PRBMDO 1098-0121 10.1103/PhysRevB.82.180502 82, 180502 (R) (2010)].
43. x y wave, since it increases the region where the sign of the order parameter is the same. The difference is whether the node is on electron or hole FS.
