Two-orbital quantum spin model of magnetism in the iron pnictides
C. Liu, D. -X. Yao, A. W. Sandvik
We study a two-orbital spin model to describe (pi,0) stripe antiferromagnetism in the iron pnictides. The "double-spin" model has an on-site Hunds's coupling and inter-site interac…

Symmetry breaking and criticality in tensor-product states
Chen Liu, Ling Wang, Anders W. Sandvik +2
We discuss variationally optimized matrix-product states for the transverse-field Ising chain, using D*D matrices with small D=2-10. For finite system size N there are energy minim…
