The recently synthesized 30$^\circ$ twisted bilayer graphene (30$^\circ$-TBG) systems are unique quasicrystal systems possessing dodecagonal symmetry with graphene's relativistic properties. We employ a real-space numerical atomistic framework that r

We present a theoretical investigation of the magnetic properties exhibited by twisted bilayer graphene systems with small twist angles, where the appearance of flat minibands strongly enhances electron-electron interaction effects. We consider a tig

We study the Landau level spectrum of bulk graphene monolayers beyond the Dirac Hamiltonian with linear dispersion. We consider an effective Wannier-like tight-binding model obtained from ab initio calculations, that includes long-range electronic ho
