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,…

Functional renormalization group approach to zero-dimensional interacting systems
R. Hedden, V. Meden, Th. Pruschke +1
We apply the functional renormalization group method to the calculation of dynamical properties of zero-dimensional interacting quantum systems. As case studies we discuss the anha…
