Chiral SDW and d + id superconductivity in the magic-angle twisted bilayer-graphene

22 Nov 2018 Liu Cheng-Cheng Zhang Li-Da Chen Wei-Qiang Yang Fan

We model the newly synthesized magic-angle twisted bilayer-graphene superconductor with two $p_{x,y}$-like Wannier orbitals on the superstructure honeycomb lattice, where the hopping integrals are constructed via the Slater-Koster formulism by symmetry analysis. The characteristics exhibited in this simple model are well consistent with both the rigorous calculations and experiment observations... (read more)
