The code in this repository implements the methods described in D. Kiese, H. U. R. Strand, K. Chen, N. Wentzell, O. Parcollet, J. Kaye, "Discrete Lehmann representation of three-point functions", arXiv:2405.06716 (2024). Some modifications/extensions of those ideas are also implemented.
It is a starting point for generalizations of the discrete Lehmann representation beyond the single-particle Green's function. The examples from the preprint above can more or less be generated using this code.
At this stage, this is a research code, and results should not be relied upon. Use at your own risk. Do not expect thorough documentation, though some can be found inside the code.
