Description:
Author(s): T. B. Wahl, H.-H. Tu, N. Schuch, and J. I. Cirac We show that projected entangled-pair states (PEPS) in two spatial dimensions can describe chiral topological states by explicitly constructing a family of such states with a nontrivial Chern number. They are ground states of two different kinds of free-fermion Hamiltonians: (i) local and gapless; (... [Phys. Rev. Lett. 111, 236805] Published Fri Dec 06, 2013
