Abstract
The authors use large-scale ab-initio density functional theory and tight binding calculations to study the role of atomic relaxation on the low energy physics of twisted bilayer graphene as a function of the twist angle, and show that the flat bands emerging close to charge neutrality can be described taking into account atomic relaxation.
