Correlated states in ABC trilayer graphene/hBN moiré heterostructures

Shortly after the discovery of correlated states and superconductivity in twisted bilayer graphene, correlated insulating states were also detected in another graphene based moiré heterostructures: the ABC trilayer aligned with hBN. The influence of the moiré on the correlated states has been questioned by the recent report of ferromagnetism and superconductivity in ABC trilayer graphene without the moiré pattern induced by hBN. Using Dynamical Mean Field Theory we have studied the signatures of Mott physics which can be induced by the moiré pattern on the trivial valence band at half-filling. In the talk we will discuss the doping and temperature dependent spectral weight reorganization characteristic of Mott correlations and absent in standard symmetry breaking transitions, and a competing antiferromagnetic state present very close to half-filling .
