On tensor network representations of the (3+1)d toric code
Clement Delcamp, Norbert Schuch
We define two dual tensor network representations of the (3+1)d toric code ground state subspace. These two representations, which are obtained by initially imposing either family…
On the stability of topological order in tensor network states
Dominic J. Williamson, Clement Delcamp, Frank Verstraete +1
We construct a tensor network representation of the 3d toric code ground state that is stable to a generating set of uniform local tensor perturbations, including those that do not…
Matrix Product States and Projected Entangled Pair States: Concepts, Symmetries, and Theorems
Ignacio Cirac, David Perez-Garcia, Norbert Schuch +1
The theory of entanglement provides a fundamentally new language for describing interactions and correlations in many body systems. Its vocabulary consists of qubits and entangled…
Entanglement order parameters and critical behavior for topological phase transitions and beyond
Mohsin Iqbal, Norbert Schuch
Topological phases are exotic quantum phases which are lacking the characterization in terms of order parameters. In this paper, we develop a unified framework based on variational…
Fractional Chiral Hinge Insulator
Anna Hackenbroich, Ana Hudomal, Norbert Schuch +2
We propose and study a wave function describing an interacting three-dimensional fractional chiral hinge insulator (FCHI) constructed by Gutzwiller projection of two non-interactin…
Tensor Networks Can Resolve Fermi Surfaces
Quinten Mortier, Norbert Schuch, Frank Verstraete +1
We demonstrate that projected entangled-pair states (PEPS) are able to represent ground states of critical, fermionic systems exhibiting both 1d and 0d Fermi surfaces on a 2D latti…
