This is a short review on selected theory developments on tensor network (TN) states for strongly correlated systems. Specifically, we briefly review the effect of symmetries in TN states, fermionic TNs, the calculation of entanglement Hamiltonians from projected entangled pair states (PEPS), and the relation between the multi-scale entanglement renormalization ansatz (MERA) and the AdS/CFT or gauge/gravity duality. We stress the role played by entanglement in the emergence of several physical…

Discrete gravity on random tensor network and holographic Rényi entropy

The boundary many-body quantum state |Ψ〉 is constructed using random tensor networks as the holographic mapping, applied to the Wheeler-deWitt wave function of bulk Euclidean discrete gravity in 3 dimensions.

Surface/State Correspondence as a Generalized Holography

We propose a new duality relation between codimension two space-like surfaces in gravitational theories and quantum states in dual Hilbert spaces. This surface/state correspondence largely

Entanglement and complexity of purification in ( 1+1 )-dimensional free conformal field theories

Finding pure states in an enlarged Hilbert space that encode the mixed state of a quantum field theory as a partial trace is necessarily a challenging task. Nevertheless, such purifications play the

Tensor Network Contractions

This lecture notes focuses on the contraction algorithms of TN as well as some of the applications to the simulations of quantum many-body systems, and revisits the TN approaches from the perspective of multi-linear algebra and quantum simulation.

Quantum criticality on a chiral ladder: An SU(2) infinite density matrix renormalization group study

In this paper we study the ground state properties of a ladder Hamiltonian with chiral $SU(2)$-invariant spin interactions, a possible first step towards the construction of truly two dimensional



Implementing global Abelian symmetries in projected entangled-pair state algorithms

A formalism to implement Abelian symmetries in two-dimensional tensor-network states is explained and benchmark results are presented that confirm the validity of these approximations in the context of projected entangled-pair state algorithms.

Renormalization and tensor product states in spin chains and lattices

This work introduces several families of such states in terms of the known renormalization procedures, and highlights some of their properties, and shows how they can be used to describe a variety of systems.

Holographic geometry of entanglement renormalization in quantum field theories

A bstractWe study a conjectured connection between AdS/CFT and a real-space quantum renormalization group scheme, the multi-scale entanglement renormalization ansatz (MERA). By making a close contact

Fermionic multiscale entanglement renormalization ansatz

In a recent contribution [P. Corboz, G. Evenbly, F. Verstraete, and G. Vidal, arXiv:0904.4151 (unpublished)] entanglement renormalization was generalized to fermionic lattice systems in two spatial

Holographic geometries of one-dimensional gapped quantum systems from tensor network states

The proposal interprets the tensor connectivity of the MERA states associated to quantum many body systems at criticality, in terms of a dual holographic geometry which accounts for the qualitative aspects of the entanglement and the correlations in these systems.

Holographic entanglement entropy: an overview

In this paper, we review recent progress on the holographic understanding of the entanglement entropy in the anti-de Sitter space/conformal field theory (AdS/CFT) correspondence. In general, the

Entanglement, tensor networks and black hole horizons

A full tensor network representation of the action of local unitary operations on the bridge state is proposed, which amounts to a Tensor network which grows in size by adding succesive layers of bridge states.

A short review on entanglement in quantum spin systems

We review some of the recent progress on the study of entropy of entanglement in many-body quantum systems. Emphasis is placed on the scaling properties of entropy for one-dimensional multi-partite

Entanglement in quantum critical phenomena.

The results establish a precise connection between concepts of quantum information, condensed matter physics, and quantum field theory, by showing that the behavior of critical entanglement in spin systems is analogous to that of entropy in conformal field theories.

Tensor Network States and Geometry
