Description:
Author(s): Fengcheng Wu, Inti Sodemann, Yasufumi Araki, Allan H. MacDonald, and Thierry Jolicoeur Electrons in graphene have four flavors associated with low-energy spin and valley degrees of freedom. The fractional quantum Hall effect in graphene is dominated by long-range Coulomb interactions, which are invariant under rotations in spin-valley space. This SU(4) symmetry is spontaneously broken... [Phys. Rev. B 90, 235432] Published Mon Dec 22, 2014
