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 …

Condensed matter theory of dipolar quantum gases

MA Baranov, M Dalmonte, G Pupillo, P Zoller - Chemical Reviews, 2012 - ACS Publications
The realization of Bose Einstein condensates (BEC) and quantum degenerate Fermi gases
with cold atoms has been a highlight of quantum physics during the past decade. Cold …

Symmetry resolved entanglement entropy of excited states in a CFT

L Capizzi, P Ruggiero… - Journal of Statistical …, 2020 - iopscience.iop.org
We report a throughout analysis of the entanglement entropies related to different symmetry
sectors in the low-lying primary excited states of a conformal field theory (CFT) with an …

Entanglement Hamiltonians of lattice models via the Bisognano-Wichmann theorem

G Giudici, T Mendes-Santos, P Calabrese, M Dalmonte - Physical Review B, 2018 - APS
The modular (or entanglement) Hamiltonian correspondent to the half-space bipartition of a
quantum state uniquely characterizes its entanglement properties. However, in the context of …

Entanglement negativity in the critical Ising chain

P Calabrese, L Tagliacozzo… - Journal of Statistical …, 2013 - iopscience.iop.org
We study the scaling of the traces of the integer powers of the partially transposed reduced
density matrix $\mathrm {Tr}({\rho} _ {A}^{{T} _ {2}})^{n} $ and of the entanglement negativity …

Detecting quantum critical points using bipartite fluctuations

S Rachel, N Laflorencie, HF Song, K Le Hur - Physical review letters, 2012 - APS
We show that the concept of bipartite fluctuations F provides a very efficient tool to detect
quantum phase transitions in strongly correlated systems. Using state-of-the-art numerical …

Spin structures and entanglement of two disjoint intervals in conformal field theories

A Coser, E Tonni, P Calabrese - Journal of Statistical Mechanics …, 2016 - iopscience.iop.org
We reconsider the moments of the reduced density matrix of two disjoint intervals and of its
partial transpose with respect to one interval for critical free fermionic lattice models. It is …

Dynamics of entanglement entropy and entanglement spectrum crossing a quantum phase transition

E Canovi, E Ercolessi, P Naldesi, L Taddia, D Vodola - Physical Review B, 2014 - APS
We study the time evolution of entanglement entropy and entanglement spectrum in a finite-
size system which crosses a quantum phase transition at different speeds. We focus on the …

Boundary fidelity and entanglement in the symmetry protected topological phase of the SSH model

J Sirker, M Maiti, NP Konstantinidis… - Journal of Statistical …, 2014 - iopscience.iop.org
We present a detailed study of the fidelity, the entanglement entropy and the entanglement
spectrum, for a dimerized chain of spinless fermions—a simplified Su–Schrieffer–Heeger …

Random matrices and entanglement entropy of trapped Fermi gases

P Calabrese, P Le Doussal, SN Majumdar - Physical Review A, 2015 - APS
We exploit and clarify the use of random matrix theory for the calculation of the entanglement
entropy of free Fermi gases. We apply this method to obtain analytic predictions for Rényi …
