Nature of the Spin Liquid State of the Hubbard Model on a Honeycomb Lattice
Nature of the Spin Liquid State of the Hubbard Model on a Honeycomb Lattice
Recent numerical work [Z. Y. Meng et al., Nature (London) 464, 847 (2010)] indicates the existence of a spin liquid (SL) phase that intervenes between the antiferromagnetic and semimetallic phases of the half filled Hubbard model on a honeycomb lattice. To better understand the nature of this exotic phase, we …
