Computation Kernel for Feynman Diagrams
Daria Gazizova, Rayan Farid, B. D. E. McNiven +3
We present a general representation for solving problems in many-body perturbation theory. By projecting the single-particle Green's function to an auxiliary space we show how one…
Lifshitz transition and triplet -wave pairing from the induced ferromagnetic plaquette via spin differentiated nonlocal interaction
Rayan Farid, Daria Gazizova, B. D. E. McNiven +1
We study the two-dimensional extended Hubbard model on a square lattice and incorporate spin-differentiated nearest neighbor (NN) interactions where the equal-spin () and u…
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…
Emergent nearest-neighbor attraction in the fully renormalized interactions of the single-band repulsive Hubbard model at weak coupling
Daria Gazizova, J. P. F. LeBlanc
We compute the perturbative expansion for the effective interaction of the half-filled 2-dimensional Hubbard model. We derive extensions of standard RPA resummations that inclu…
