Mean Field Decoupling of Single Impurity Anderson Model through Auxiliary Majorana Fermions

Published in Annals of Physics, 2025

Consistency of potential energy in the dynamical vertex approximation

Published in Physical Review B, 2022

This paper extends the existing ladder dynamical vertex approximation to include consistency of the potential energies between one- and two-particle level. The effects near the antiferromagnetic phase transition in the Hubbard model on the 3D simple cubic lattice are discussed.
