The manuscript that it refers to does not contain any calculations concerning superconducivity of the material, so it cannot say anything about it aside from vague guesses. There are no manuscripts I know on arXiv that contain calculations that suggest the material &quot;should&quot; be superconducting. This paper and several other discuss flat bands, but as noted in https://arxiv.org/abs/2308.05143 and elsewhere flat bands are no reason to expect superconductivity, especially the kinds that this material supports. So there is no theoretical support…</p><p><a href="https://hackerpaper.kaipfister.de/p/2308.05143/">Paper and discussion history</a>. A mention is not an endorsement.</p>cond-mat.supr-con
