Simulation of strongly correlated fermions in two spatial dimensions with fermionic Projected Entangled-Pair States
We explain how to implement, in the context of projected entangled-pair states (PEPS), the general procedure of fermionization of a tensor network introduced in [P. Corboz, G. Vidal, Phys. Rev. B 80, 165129 (2009)]. The resulting fermionic PEPS, similar to previous proposals, can be used to study the ground state of interacting fermions on a two-dimensional lattice. As in the bosonic case, the ...

متن کاملAssessing the accuracy of projected entangled-pair states on infinite lattices
Generalizations of the density-matrix renormalization group method have long been sought after. In this paper, we assess the accuracy of projected entangled-pair states on infinite lattices by comparing with Quantum Monte Carlo results for several non-frustrated spin-1/2 systems. Furthermore, we apply the method to a frustrated quantum system. PACS numbers: 03.67.-a, 75.10.-b, 75.40.Mg, 03.65.U...
