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
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
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
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 …

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
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) …
