Featured Research: Ferromagnetism with a New Twist

In a new study published in Physical Review Letters, OU postdoc Kangjun Seo and physics professor Bruno Uchoa have found numerical evidence of a novel Mott state that exhibits ferromagnetism at low temperatures. Recent experiments found that when two sheets of graphene are twisted by a very small angle, dubbed a 'magic angle', the combined system behaves as a very strongly correlated system in ways that remind several of the outstanding properties observed in high temperature superconductors.…
