29. In Ref. [7], Eq. (D4), it is argued that the real part of the self-energy in the range of frequencies W ω U must have the behavior Re Σ (k, ω) = - n 2 - n ω + const. Hence, at a density n = 0.0414, we expect Re Σ (k, ω) = - 0.0212 ω + const., as found numerically.
30. This is easy to see from the definition of the scattering amplitude and its result in the ladder scheme:
31. where we used Eq.. The spectral density of γ is now easy to find
32. leading to the quoted result.
