Description:
Author(s): Noel A. García-Martínez, Adolfo G. Grushin, Titus Neupert, Belén Valenzuela, and Eduardo V. Castro We investigate the fate of interaction-driven phases in the half-filled honeycomb lattice for finite systems via exact diagonalization with nearest- and next-nearest-neighbor interactions. We find evidence for a charge density wave phase, a Kekulé bond order, and a sublattice charge-modulated phase ... [Phys. Rev. B 88, 245123] Published Wed Dec 18, 2013
