【 摘 要 】

We compute the two-point (equal-time) electronic Green function in a Tomonaga-Luttinger system with long-range electron-electron interactions. We obtain an analytical expression for a super long-range potential of the form V(x) = e(2)d(-epsilon)/\x\(1-epsilon). As a consistency check of our computational technique we also consider the particular case of a Coulomb potential. Our result confirms the exp - C(log x)(3/2) long-distance behavior first obtained by Schulz.
