Dynamic scaling in the vicinity of the Luttinger liquid fixed point
Tom Busche, Lorenz Bartosch, Peter Kopietz
We calculate the single-particle spectral function A (k, omega) of a one-dimensional Luttinger liquid by means of a functional renormalization group (RG) approach. Given an infrare…

Exact renormalization group flow equations for non-relativistic fermions: scaling towards the Fermi surface
Peter Kopietz, Tom Busche
We construct exact functional renormalization group (RG) flow equations for non-relativistic fermions in arbitrary dimensions, taking into account not only mode elimination but als…

How does a quadratic term in the energy dispersion modify the single-particle Green's function of the Tomonaga-Luttinger model?
Tom Busche, Peter Kopietz
We calculate the effect of a quadratic term in the energy dispersion on the low-energy behavior of the Green's function of the spinless Tomonaga-Luttinger model (TLM). Assuming tha…
