Abstract: One of the most active research topics in graphene has been the search of magnetism.  In the recent past, and based on Lieb’s theorem [1], the research has been focused on point defects like vacancies or adsorbed single atoms like hydrogen or fluorine [2,3]. Very recently, the work of Prof. P. Jarillo-Herrero’s group at MIT [4] has opened the possibility of correlated states in defect’s free twisted graphene bilayers. These issues will be discussed in the talk along recent results on magnetic moments in twisted bilayers [5].
