Comment on paper: Evidence for Dirac flat band superconductivity enabled by quantum geometry, Nature 614, 440 (2023)
V. R. Shaginyan, A. Z. Msezane, G. S. Japaridze
We demonstrate that an absolutely flat band retains the superconducting state at . When the flat band disappears, since it must be modified by the superconducting…
