Note from the submitting author copied here:

This submission presents the Analytic Continuation component, an independent part of the GreenX software suite. The scope of this publication is the analytic continuation of complex-valued functions using Padé approximants, with a Fortran API. The primary application of this component is in electronic structure methods, though it is broadly applicable across fields requiring analytic continuation. A previous JOSS publication covered the TimeFrequency component, which provides minimax Time-Frequency Grids for the random phase approximation and GW methods. This new submission about the Analytic Continuation component expands the functionality of GreenX without overlap with the previously published work.

[arfon]

@moritzleucke – thanks for your note on the submission form. Could you please link directly to the areas of the codebase that are new here (i.e., should be reviewed as a new contribution)?

Additionally, we're currently managing a large backlog of submissions and the editor most appropriate for your area is already rather busy.

For now, we will need to waitlist this paper and process it as the queue reduces. Thanks for your patience!

[moritzleucke]

Dear @arfon,

Thank you for reaching out. The new addition to the codebase is the entire folder "GX-AnalyticContinuation" (https://github.com/nomad-coe/greenX/tree/main/GX-AnalyticContinuation) within the GreenX repository. This folder contains the analytic continuation component, which is the focus of the newly submitted paper.

It has no overlap with the time-frequency component in the folder "GX-TimeFrequency", that was published in a previous joss paper (https://doi.org/10.21105/joss.05570).

Best,
Moritz Leucke
