Confined coherence in quasi-one-dimensional metals
Sascha Ledowski, Peter Kopietz
We present a functional renormalization group calculation of the effect of strong interactions on the shape of the Fermi surface of weakly coupled metallic chains. In the regime wh…

Fermi surface renormalization and confinement in two coupled metallic chains
Sascha Ledowski, Peter Kopietz
Using a non-perturbative functional renormalization group approach involving both fermionic and bosonic fields we calculate the interaction-induced change of the Fermi surface of s…

Self-consistent Fermi surface renormalization of two coupled Luttinger liquids
Sascha Ledowski, Peter Kopietz, Alvaro Ferraz
Using functional renormalization group methods, we present a self-consistent calculation of the true Fermi momenta k_F^a (antibonding band) and k_F^b (bonding band) of two spinless…
