KeldyshQFT: A C++ codebase for real-frequency multiloop functional renormalization group and parquet computations of the single-impurity Anderson model
Nepomuk Ritz, Anxiang Ge, Elias Walter +3
We provide a detailed exposition of our computational framework designed for the accurate calculation of real-frequency dynamical correlation functions of the single-impurity Ander…

Real-frequency quantum field theory applied to the single-impurity Anderson model
Anxiang Ge, Nepomuk Ritz, Elias Walter +3
A major challenge in the field of correlated electrons is the computation of dynamical correlation functions. For comparisons with experiment, one is interested in their real-frequ…
