Journal ArticleDOI
Anyons and matrix product operator algebras
Nick Bultinck,Michaël Mariën,Dominic J. Williamson,Mehmet B. Şahinoğlu,Jutho Haegeman,Frank Verstraete,Frank Verstraete +6 more
TL;DR: In this paper, the authors present a systematic study of matrix product operators and show how this relates entanglement properties of projected entangled-pair states to the formalism of fusion tensor categories.
Journal ArticleDOI
Entanglement rates and area laws.
TL;DR: An upper bound on the maximal rate at which a Hamiltonian interaction can generate entanglement in a bipartite system is proved and the scaling of this bound as a function of the subsystem dimension on which the Hamiltonian acts nontrivially is optimal and is exponentially improved over previously known bounds.
Journal ArticleDOI
Entanglement of Distillation for Lattice Gauge Theories.
Karel Van Acoleyen,Nick Bultinck,Jutho Haegeman,Michaël Mariën,Volkher B. Scholz,Frank Verstraete,Frank Verstraete +6 more
TL;DR: The usual entanglement entropy for a spatial bipartition can be written as the sum of an undistillable gauge part and of another part corresponding to the local operations and classical communication distillableEntanglement, which is obtained by depolarizing the local superselection sectors.
Journal ArticleDOI
Excitations and the tangent space of projected entangled-pair states
TL;DR: In this article, a variational ansatz for elementary excitations on top of projected entangled-pair states (PEPS) ground states was proposed to compute gaps, dispersion relations, and spectral weights directly in the thermodynamic limit.
Journal ArticleDOI
Renormalization Group Flows of Hamiltonians Using Tensor Networks.
TL;DR: It is emphasized that the key difference between tensor network approaches and Kadanoff's spin blocking method can be understood in terms of a change of the local basis at every decimation step, a property which is crucial to overcome the area law of mutual information.
