Simulation of interacting fermions with entanglement renormalization

We propose an algorithm to simulate interacting fermions on a two-dimensional lattice. The approach is an extension of the entanglement renormalization technique [Phys. Rev. Lett. 99, 220405 (2007)] and the related multiscale entanglement renormalization ansatz. Benchmark calculations for free and interacting fermions on lattices ranging from 6×6 to 162×162 sites with periodic boundary conditions confirm the validity of this proposal. © 2010 The American Physical Society
