Superconducting junctions with flat bands
P. Virtanen, R. P. S. Penttilä, P. Törmä +3
We analyze the properties of flat-band superconductor junctions that behave differently from ordinary junctions containing only metals with Fermi surfaces. In particular, we show h…

Magnetoelectric effects in diffusive two-dimensional superconductors studied by the nonlinear model
P. Virtanen
We describe a numerical approach to modeling magnetoelectric effects generated by spin-orbit coupling in inhomogeneous diffusive 2D superconductors. It is based on direct minimizat…

Probing the flat-band limit of the superconducting proximity effect in Twisted Bilayer Graphene Josephson junctions
A. Diez-Carlon, J. Diez-Merida, P. Rout +13
While extensively studied in normal metals, semimetals and semiconductors, the superconducting (SC) proximity effect remains elusive in the emerging field of flat-band systems. In…
