Artificial honeycomb lattice as a platform for correlated Dirac fermions

This paper theoretically investigates conditions to achieve strongly correlated electrons in an artificial honeycomb lattice formed by a triangular array of antidots in a 2D electron gas. By tuning the antidot radius and screening length, an antiferromagnetic Mott insulator phase emerges, indicating strongly correlated Dirac fermions.
