    • 2 regime for Im Σ is rather narrow in energy and will be washed out by finite temperature effects, precluding their observation experimentally except in the heavily overdoped limit.

    • note
    • In real materials, the phonon density of states has a large spread in energy which also acts to smear the S shape; see Verga et al. and Schachinger et al. of Ref. 27. However, this broadening also reduces the renormalization of the Fermi velocity, as can be seen from Eq. (49).

    • But if the bare Green's function is assumed to be a Luttinger liquid, then the S shape from an Einstein mode is also smeared out; see I.P. Bindloss and S.A. Kivelson, cond-mat/0402457 (unpublished).
