Transformer spin-triplet superconductivity at the onset of isospin order in bilayer graphene

Abstract

The recently discovered superconductivity in Bernal bilayer graphene features unique behavior that distinguishes it from conventional superconductors. Firstly, the onset of superconductivity is associated with the emergence of an isospin-polarized phase, driven by Stoner instability. Secondly, the superconductivity is activated by a magnetic field and persists beyond the Pauli limit. These properties have sparked the interest of researchers and prompted the search for a pairing mechanism that can account for these findings. This paper reports on recent progress in this quest.\hskip-0.22em
