Summary
I am not sure if it is suitable to ask about the vertex asymptotic feature of the CTQMC here for the DMFT lattice susceptibility. However, it may be good to post here for discussion.
Motivation
I have performed the tutorial of the DMFT lattice susceptibility of the one-band Hubbard model: tutorial. I noticed that the vertex $\Gamma_m$ has strong oscillation at high frequency.
It seems to me that the high-frequency vertex asymptotic ref is not applied here. Therefore, I was wondering how one could incorporate the vertex asymptotic into the vertex calculation using the impurity solver like CTHYB and w2dynamics.
Implementation
If the question can be addressed here with simple words and references, there's no need to implement any new features.
Thank you very much in advance!
