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…
Multiloop flow equations for single-boson exchange fRG
Marcel Gievers, Elias Walter, Anxiang Ge +2
The recently introduced single-boson exchange (SBE) decomposition of the four-point vertex of interacting fermionic many-body systems is a conceptually and computationally appealin…
Global phase diagram of a spin-orbital Kondo impurity model and the suppression of Fermi-liquid scale
Y. Wang, E. Walter, S. -S. B. Lee +4
Many correlated metallic materials are described by Landau Fermi-liquid theory at low energies, but for Hund metals the Fermi-liquid coherence scale is found to be…
Uncovering Non-Fermi-Liquid Behavior in Hund Metals: Conformal Field Theory Analysis of an SU(2)SU(3) Spin-Orbital Kondo Model
E. Walter, K. M. Stadler, S. -S. B. Lee +4
Hund metals have attracted attention in recent years due to their unconventional superconductivity, which supposedly originates from non-Fermi-liquid (NFL) properties of the normal…
Breakdown of the Law of Reflection at a Disordered Graphene Edge
E. Walter, T. Ö. Rosdahl, A. R. Akhmerov +1
The law of reflection states that smooth surfaces reflect waves specularly, thereby acting as a mirror. This law is insensitive to disorder as long as its length scale is smaller t…
