Real-Frequency Diagrammatics with Pole Representations
Rayan Farid, Lei Zhang, Aiman Al-Eryani +2
Finite-temperature many-body theories are typically formulated in imaginary time, where they are amenable to efficient numerical treatment. However, the extraction of spectral prop…
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…
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…
Pairing susceptibility of the two-dimensional Hubbard model in the thermodynamic limit
Rayan Farid, Maxence Grandadam, J. P. F. LeBlanc
We compute the diagrammatic expansion of the particle-particle susceptibility via algorithmic Matsubara integration and compute the correlated pairing susceptibility in the thermod…
