Low-energy effective interactions beyond the constrained random-phase approximation by the functional renormalization group
Michael Kinza, Carsten Honerkamp
In the derivation of low-energy effective models for solids targeting the bands near the Fermi level, the constrained random phase approximation (cRPA) has become an appreciated to…
Two-particle-correlations in a functional renormalization group scheme using a dynamical mean-field theory approach
Michael Kinza, Carsten Honerkamp
We apply a recently introduced hybridization-flow functional renormalization group scheme for Anderson-like impurity models as an impurity solver in a dynamical mean-field theory (…
An alternative functional renormalization group approach to the single impurity Anderson model
Michael Kinza, Jutta Ortloff, Johannes Bauer +1
We present an alternative functional renormalization group (fRG) approach to the single-impurity Anderson model at finite temperatures. Starting with the exact self-energy and inte…
Effective low-energy Hamiltonians for interacting nanostructures
Michael Kinza, Jutta Ortloff, Carsten Honerkamp
We present a functional renormalization group (fRG) treatment of trigonal graphene nanodiscs and composites thereof, modeled by finite-size Hubbard-like Hamiltonians with honeycomb…
