Research paperTheoreticalComputational Kinetic ModelEliashberg Theory and Superfluid Stiffness of Band-Off-Diagonal Pairing in Twisted GrapheneBernhard Putzer, Mathias S. Scheurer2025·10.1038/s41567-·arXiv:2501.12435AbstractWe study band-off-diagonal pairing in twisted graphene within Eliashberg theory. We show that symmetry can prohibit admixture of intraband and interband pairing components for the leading-order interactions, while even- and odd-frequency components can mix. We compute the electronic spectral function by analytic continuation and analyze the superfluid stiffness including multiband and quantum-geometric effects.Read more
