Functional renormalization group approach to correlated fermion systems
Walter Metzner, Manfred Salmhofer, Carsten Honerkamp +2
Numerous correlated electron systems exhibit a strongly scale-dependent behavior. Upon lowering the energy scale, collective phenomena, bound states, and new effective degrees of f…
A finite-frequency functional RG approach to the single impurity Anderson model
C. Karrasch, R. Hedden, R. Peters +3
We use the Matsubara functional renormalization group (FRG) to describe electronic correlations within the single impurity Anderson model. In contrast to standard FRG calculations,…
Comment on ``Bethe Ansatz Results for the 4f-Electron Spectra of a Degenerate Anderson Model ''
O. Gunnarsson, K. Schonhammer
In a recent letter, Zvyagin calculates the density of states for 4f electrons coupled to a conduction band in the framework of the Bethe ansatz (BA) solution for the degenerate And…
A single impurity in a Luttinger liquid: How it "cuts" the chain
V. Meden, W. Metzner, U. Schollwoeck +1
Using a fermionic renormalization group method we present a simple real space picture of the strong influence an impurity has on the electronic properties of a Luttinger liquid. We…
