Our Python package `adapol` ("add a pole") implements an adaptive pole-fitting procedure introduced in [@huang2023; @huang2024_3].
The method first uses the AAA rational approximation algorithm [@nakatsukasa2018] to find an initial guess for the pole locations $E_p$. It then uses non-convex optimization and singular value decomposition to refine $E_p$ and obtain $v_p$.
Variants of this procedure have been shown to provide an accurate and compact fit for Matsubara data in a black-box and noise-robust manner, enabling new algorithms for dynamical mean-field theory [@mejuto2020efficient] and Feynman diagram evaluation [huang2024_3]. For example, [huang2024_3] demonstrates that the procedure yields a more compact pole approximation than the generic discrete Lehmann representation [@kaye2022discrete] for fixed objective functions.
