A practical introduction to tensor networks: Matrix product states and projected entangled pair states
R Orús - Annals of physics, 2014 - Elsevier
This is a partly non-technical introduction to selected topics on tensor network methods,
based on several lectures and introductory seminars given on the subject. It should be a …

Observation of a symmetry-protected topological phase of interacting bosons with Rydberg atoms
The concept of topological phases is a powerful framework for characterizing ground states
of quantum many-body systems that goes beyond the paradigm of symmetry breaking …

Entanglement spectrum of a topological phase in one dimension
We show that the Haldane phase of S= 1 chains is characterized by a double degeneracy of
the entanglement spectrum. The degeneracy is protected by a set of symmetries (either the …

Gapped phases with non-invertible symmetries:(1+ 1) d
We propose a general framework to characterize gapped infra-red (IR) phases of theories
with non-invertible (or categorical) symmetries. In this paper we focus on (1+ 1) d gapped …

Long-range entanglement from measuring symmetry-protected topological phases
A fundamental distinction between many-body quantum states are those with short-and long-
range entanglement (SRE and LRE). The latter cannot be created by finite-depth circuits …

Classification of gapped symmetric phases in one-dimensional spin systems
Quantum many-body systems divide into a variety of phases with very different physical
properties. The questions of what kinds of phases exist and how to identify them seem hard …

Entanglement of exact excited states of Affleck-Kennedy-Lieb-Tasaki models: Exact results, many-body scars, and violation of the strong eigenstate thermalization …
We obtain multiple exact results on the entanglement of the exact excited states of
nonintegrable models we introduced in Phys. Rev. B 98, 235155 (2018) 10.1103/PhysRevB …

Topological phases of fermions in one dimension
L Fidkowski, A Kitaev - Physical Review B—Condensed Matter and Materials …, 2011 - APS
In this paper we show how the classification of topological phases in insulators and
superconductors is changed by interactions, in the case of one-dimensional systems. We …

Hand-waving and interpretive dance: an introductory course on tensor networks
The curse of dimensionality associated with the Hilbert space of spin systems provides a
significant obstruction to the study of condensed matter systems. Tensor networks have …
