Decomposing imaginary time Feynman diagrams using separable basis functions: Anderson impurity model strong coupling expansion
Jason Kaye, Zhen Huang, Hugo U. R. Strand +1
We present a deterministic algorithm for the efficient evaluation of imaginary time diagrams based on the recently introduced discrete Lehmann representation (DLR) of imaginary tim…

Low rank Green's function representations applied to dynamical mean-field theory
Nan Sheng, Alexander Hampel, Sophie Beck +4
Several recent works have introduced highly compact representations of single-particle Green's functions in the imaginary time and Matsubara frequency domains, as well as efficient…
