Algorithms for entanglement renormalization

Evenbly, G., Vidal, G.

Understand

We describe an iterative method to optimize the multi-scale entanglement renormalization ansatz (MERA) for the low-energy subspace of local Hamiltonians on a D-dimensional lattice.

  • For translation invariant systems the cost of this optimization is logarithmic in the linear system size.
  • Specialized algorithms for the treatment of infinite systems are also described.
  • Benchmark simulation results are presented for a variety of 1D systems, namely Ising, Potts, XX and Heisenberg models.
