Abstract: Graphene-like lattices offer in spite of lacking geometric frustration a promising playground for novel phases for fermions due to enhanced fluctuations as a result of low dimensionality, low coordination, and a vanishing density of states at the neutrality point. We review in this talk different phases appearing in quantum Monte Carlo simulations due to correlation in interplay with structure in single layer and bilayer systems, spin-orbit interaction, and a number N > 2 of flavors. The latter case, originally introduced by theoretical motivations can nowadays be realized experimentally with ultra-cold alkaline-earth atoms in optical lattices.
