Entanglement renormalization, scale invariance, and quantum criticality
Robert N. C. Pfeifer, Glen Evenbly, Guifre Vidal
The use of entanglement renormalization in the presence of scale invariance is investigated. We explain how to compute an accurate approximation of the critical ground state of a l…
Explicit tensor network representation for the ground states of string-net models
O. Buerschaper, M. Aguado, G. Vidal
The structure of string-net lattice models, relevant as examples of topological phases, leads to a remarkably simple way of expressing their ground states as a tensor network const…
Exact entanglement renormalization for string-net models
Robert Koenig, Ben W. Reichardt, Guifre Vidal
We construct an explicit renormalization group (RG) transformation for Levin and Wen's string-net models on a hexagonal lattice. The transformation leaves invariant the ground-stat…
