Feynman diagrammatics based on discrete pole representations: A path to renormalized perturbation theories
Daria Gazizova, Lei Zhang, Emanuel Gull +1
By merging algorithmic Matsubara integration with discrete pole representations we present a procedure to generate fully analytic closed form results for impurity problems at fixed…

Pairing susceptibility in the weakly interacting multilayer Hubbard model evaluated by direct perturbative expansion
Rayan Farid, J. P. F. LeBlanc
We present a systematic study of the interaction, doping, and layer dependence of the -wave pairing susceptibility of the Hubbard model for a stacked 2D square lattice…
