Faster Methods for Contracting Infinite 2D Tensor Networks
M. T. Fishman, L. Vanderstraeten, V. Zauner-Stauber +2
We revisit the corner transfer matrix renormalization group (CTMRG) method of Nishino and Okunishi for contracting two-dimensional (2D) tensor networks and demonstrate that its per…
Error estimates for extrapolations with matrix-product states
C. Hubig, J. Haegeman, U. Schollwöck
We introduce a new error measure for matrix-product states without requiring the relatively costly two-site density matrix renormalization group (2DMRG). This error measure is base…
Global anomaly detection in two-dimensional symmetry-protected topological phases
Nick Bultinck, Robijn Vanhove, Jutho Haegeman +1
Edge theories of symmetry-protected topological phases are well-known to possess global symmetry anomalies. In this work we focus on two-dimensional bosonic phases protected by an…
Fermionic projected entangled-pair states and topological phases
Nick Bultinck, Dominic J. Williamson, Jutho Haegeman +1
We study fermionic matrix product operator algebras and identify the associated algebraic data. Using this algebraic data we construct fermionic tensor network states in two dimens…
Bridging Perturbative Expansions with Tensor Networks
Laurens Vanderstraeten, Michaël Mariën, Jutho Haegeman +3
We demonstrate that perturbative expansions for quantum many-body systems can be rephrased in terms of tensor networks, thereby providing a natural framework for interpolating pert…
Entanglement phases as holographic duals of anyon condensates
Kasper Duivenvoorden, Mohsin Iqbal, Jutho Haegeman +2
Anyon condensation forms a mechanism which allows to relate different topological phases. We study anyon condensation in the framework of Projected Entangled Pair States (PEPS) whe…
