Following the recent progresses made by the Yazdani group in visualizing broken symmetries and topological states caused by the interaction between electrons in graphene under high magnetic field , Markus Morgenstern and Mark Goerbig have released Perspective article in Science , where they review in a very accessible language the basic physics beyond the observed effects.
