Theoretical study on ambient pressure superconductivity in La$_3$Ni$_2$O$_7$ thin films : structural analysis, model construction, and robustness of $s\pm$-wave pairing

Hirofumi Sakakibara, Kazuhiko Kuroki, Kensei Ushio, Masayuki Ochi, Ryota Mizuno, Shu Kamiyama, Yuto Hoshi

s±-wave pairing symmetry remains robust in La3Ni2O7 thin films at ambient pressure because it is driven by finite-energy spin fluctuations.

Claims

C1strongest claim

s±-wave pairing symmetry remains robust regardless of these details in the band structure. The robustness of the s±-wave pairing mainly owes to the fact that it is mediated by finite energy spin fluctuations, which are insensitive to the details of the Fermi surface topology and give rise to a nearly-momentum-independent gap function for the interlayer d3z2-r2 pairing in the orbital representation.

C2weakest assumption

The fluctuation exchange approximation, which takes into account the full momentum and frequency dependencies, sufficiently captures the pairing interaction and Tc scale in these nickelate systems when applied to the constructed tight-binding models.

C3one line summary

s±-wave pairing remains robust in La3Ni2O7 thin-film models under FLEX, but reduced Tc is reproduced only when using the experimental structure's small interlayer hopping.
