Formatted abstract
Entanglement renormalization techniques are applied to numerically investigate the ground state of the spin-½ Heisenberg model on a kagome lattice. Lattices of N={36,144,∞} sites with periodic boundary conditions are considered. For the infinite lattice, the best approximation to the ground state is found to be a valence bond crystal with a 36-site unit cell, compatible with a previous proposal. Its energy per site, E=-0.43221, is an exact upper bound and is lower than the energy of any previous (gapped or algebraic) spin liquid candidate for the ground state. © 2010 The American Physical Society.
