Interactions and phase transitions on graphene's honeycomb lattice | | Igor F. Herbut
; | | Date: |
7 Jun 2006 | | Abstract: | The low-energy theory of interacting electrons on graphene’s two-dimensional honeycomb lattice is derived and discussed. In particular, the Hubbard model in the large-N limit is shown to have a semi-metal - antiferromagnetic insulator quantum critical point in the universality class of the Gross-Neveu model. The same equivalence is conjectured to hold in the physical case N=2, and its consequences for various physical quantities are examined. The effects of the long-range Coulomb interaction and of the magnetic field are discussed. | | Source: | arXiv, cond-mat/0606195 | | Other source: | [GID 137815] pmid17155272 | | Services: | Forum | Review | PDF | Favorites | |
