local correlations between quantum objects, and is at the heart of quantum information …

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

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 …

[图书][B] Holographic entanglement entropy

M Rangamani, T Takayanagi, M Rangamani… - 2017 - Springer
The discussions in § 2 and § 3 make it rather clear that while we have to evaluate a
sequence of functional integrals to compute the Rényi entropies, these are rather complex …

Hidden Fermi surfaces in compressible states of gauge-gravity duality

L Huijse, S Sachdev, B Swingle - Physical Review B—Condensed Matter and …, 2012 - APS
