Reduced density matrices and entanglement entropy in free lattice models
Ingo Peschel,Viktor Eisler +1 more
TL;DR: In this article, the properties of reduced density matrices for free fermionic or bosonic many-particle systems in their ground state are reviewed for various one-dimensional situations, including also the evolution after global or local quenches.

Evolution of entanglement after a local quench
Viktor Eisler,Ingo Peschel +1 more
TL;DR: In this paper, the authors studied free electrons on an infinite half-filled chain, starting in the ground state with a bond defect, and found a logarithmic increase of the entanglement entropy after the defect is removed, followed by a slow relaxation towards the value of the homogeneous chain.

On the partial transpose of fermionic Gaussian states
Viktor Eisler,Zoltán Zimborás +1 more
TL;DR: In this article, the action of the partial transposition on the density matrix of fermionic systems is studied, and it is shown that, with a suitable choice of basis, these states are transformed into a linear combination of two Gaussian operators that are uniquely defined in terms of the covariance matrix of the original state.

Entanglement negativity in the harmonic chain out of equilibrium
TL;DR: In this paper, the entanglement in a chain of harmonic oscillators driven out of equilibrium by preparing the two sides of the system at different temperatures, and subsequently joining them together was studied.
