제목: Wess-Zumino-Witten Terms in Graphene Landau Levels

초록: We consider the interplay between the antiferromagnetic and Kekulé valence bond solid orderings in the zero energy Landau levels of neutral monolayer and bilayer graphene. We establish the presence of Wess-Zumino-Witten terms between these orders and present two independent proofs. This topological field theory for the two order parameters implies that their quantum fluctuations are described by the deconfined critical theories of quantum spin systems. We also present implications for experiments, including the possible presence of excitonic superfluidity in bilayer graphene.
