Bosonization of interacting fermions in arbitrary dimension beyond the Gaussian approximation
Peter Kopietz, Joachim Hermisson, Kurt Schoenhammer
We use our recently developed functional bosonization approach to bosonize interacting fermions in arbitrary dimension beyond the Gaussian approximation. Even in the fini…

Anomalous scaling and spin-charge separation in coupled chains
Peter Kopietz, Volker Meden, Kurt Schoenhammer
We use a bosonization approach to show that the three dimensional Coulomb interaction in coupled metallic chains leads to a Luttinger liquid for vanishing inter-chain hopping $t_{\…
