Description:
Author(s): R. Rodríguez-Guzmán, K. W. Schmid, Carlos A. Jiménez-Hoyos, and Gustavo E. Scuseria We present a symmetry-projected configuration mixing scheme to describe ground and excited states, with well defined quantum numbers, of the two-dimensional Hubbard model with nearest-neighbor hopping and periodic boundary conditions. Results for the half-filled 2×4 , 4×4 , and 6×6 lattices as well as... [Phys. Rev. B 85, 245130] Published Tue Jun 26, 2012
