Antiferromagnetism and chiral d-wave superconductivity from an effective model for twisted bilayer graphene
Xingyu Gu, Chuan Chen, Jia Ning Leaw +4
Starting from the strong-coupling limit of an extended Hubbard model, we develop a spin-fermion theory to study the insulating phase and pairing symmetry of the superconducting pha…

Singlet superconductivity enhanced by charge order in nested twisted bilayer graphene Fermi surfaces
Evan Laksono, Jia Ning Leaw, Alexander Reaves +4
Using the continuum model for low energy non-interacting electronic structure of moiré van der Waals heterostructures developed by Bistritzer and MacDonald [1], we study the compet…
