Entanglement negativity in a fermionic chain with dissipative defects: Exact results
Fabio Caceffo, Vincenzo Alba
We investigate the dynamics of the fermionic logarithmic negativity in a free-fermion chain with a localized loss, which acts as a dissipative impurity. The chain is initially prep…
Logarithmic entanglement scaling in dissipative free-fermion systems
Antonio D'Abbruzzo, Vincenzo Alba, Davide Rossini
We study the quantum information spreading in one-dimensional free-fermion systems in the presence of localized thermal baths. We employ a nonlocal Lindblad master equation to desc…
Entangled multiplets and unusual spreading of quantum correlations in a continuously monitored tight-binding chain
Federico Carollo, Vincenzo Alba
We analyze the dynamics of entanglement in a paradigmatic noninteracting system subject to continuous monitoring of the local excitation densities. Recently, it was conjectured tha…
Logarithmic negativity in out-of-equilibrium open free-fermion chains: An exactly solvable case
Vincenzo Alba, Federico Carollo
We derive the quasiparticle picture for the fermionic logarithmic negativity in a tight-binding chain subject to gain and loss dissipation. We focus on the dynamics after the quant…
Growth of Rényi Entropies in Interacting Integrable Models and the Breakdown of the Quasiparticle Picture
Bruno Bertini, Katja Klobas, Vincenzo Alba +2
Rényi entropies are conceptually valuable and experimentally relevant generalisations of the celebrated von Neumann entanglement entropy. After a quantum quench in a clean quantum…
Rise and fall, and slow rise again, of operator entanglement under dephasing
David Wellnitz, Guillermo Preisser, Vincenzo Alba +2
The operator space entanglement entropy, or simply 'operator entanglement' (OE), is an indicator of the complexity of quantum operators and of their approximability by Matrix Produ…
