Quantum entanglement in condensed matter systems

N Laflorencie - Physics Reports, 2016 - Elsevier
This review focuses on the field of quantum entanglement applied to condensed matter
physics systems with strong correlations, a domain which has rapidly grown over the last …

Nature of the Spin-Liquid Ground State of the Heisenberg Model on the Kagome Lattice

S Depenbrock, IP McCulloch, U Schollwöck - Physical review letters, 2012 - APS
We perform a density-matrix renormalization group (DMRG) study of the S= 1 2 Heisenberg
antiferromagnet on the kagome lattice to identify the conjectured spin liquid ground state …

Quasiparticle statistics and braiding from ground-state entanglement

Y Zhang, T Grover, A Turner, M Oshikawa… - Physical Review B …, 2012 - APS
Topologically ordered phases are gapped states, defined by the properties of excitations
when taken around one another. Here we demonstrate a method to extract the statistics and …

Fractional quantum Hall physics in topological flat bands

SA Parameswaran, R Roy, SL Sondhi - Comptes Rendus Physique, 2013 - Elsevier
We present a pedagogical review of the physics of fractional Chern insulators with a
particular focus on the connection to the fractional quantum Hall effect. While the latter …

Classification of symmetry enriched topological phases with exactly solvable models

A Mesaros, Y Ran - Physical Review B—Condensed Matter and Materials …, 2013 - APS
Recently, a new class of quantum phases of matter—symmetry protected topological states,
such as topological insulators—has attracted much attention. In presence of interactions …

Magic-state resource theory for the ground state of the transverse-field Ising model

SFE Oliviero, L Leone, A Hamma - Physical Review A, 2022 - APS
Ground states of quantum many-body systems are both entangled and possess a kind of
quantum complexity, as their preparation requires universal resources that go beyond the …

Quantum loop topography for machine learning

Y Zhang, EA Kim - Physical review letters, 2017 - APS
Despite rapidly growing interest in harnessing machine learning in the study of quantum
many-body systems, training neural networks to identify quantum phases is a nontrivial …

Measuring entanglement entropy of a generic many-body system with a quantum switch

DA Abanin, E Demler - Physical review letters, 2012 - APS
Entanglement entropy has become an important theoretical concept in condensed matter
physics because it provides a unique tool for characterizing quantum mechanical many …

Entanglement entropy of gapped phases and topological order in three dimensions

T Grover, AM Turner, A Vishwanath - Physical Review B—Condensed Matter …, 2011 - APS
We discuss entanglement entropy of gapped ground states in different dimensions, obtained
on partitioning space into two regions. For trivial phases without topological order, we argue …

Rényi entropies for free field theories

IR Klebanov, SS Pufu, S Sachdev, BR Safdi - Journal of High Energy …, 2012 - Springer
A bstract Rényi entropies S q are useful measures of quantum entanglement; they can be
calculated from traces of the reduced density matrix raised to power q, with q≥ 0. For (d+ 1) …
