Figure 1.

Superconducting gap manifested in BQP spectra. The data are for underdoped and overdoped Bi2212 samples with Tc = 66 and 80 K (UD66 and OD80, respectively) [8]. (a) Momentum-space diagram for an off-node angle, θ, and a bonding-band (BB) Fermi surface along which the ARPES spectra were taken. (b, c) Symmetrized energy distribution curves (colored circles) and their fits (black curves). (d, e) ARPES spectral images as a function of energy ω and sin 2θ. Superimposed are the gap energies (yellow circles) and high-harmonic fit (yellow curve) as functions of sin 2θ.
