Charge order and antiferromagnetism in twisted bilayer graphene from the variational cluster approximation
B. Pahlevanzadeh, P. Sahebsara, D. Sénéchal
We study the possibility of charge order at quarter filling and antiferromagnetism at half-filling in a tight-binding model of magic angle twisted bilayer graphene. We build on the…

Chiral -wave superconductivity in twisted bilayer graphene from dynamical mean field theory
B. Pahlevanzadeh, P. Sahebsara, D. Sénéchal
We apply cluster dynamical mean field theory with an exact-diagonalization impurity solver to a Hubbard model for magic-angle twisted bilayer graphene, built on the tight-binding m…
