Long-Lived Mesoscopic Entanglement Between Two Damped Infinite Harmonic Chains
We consider two chains, each made of N independent oscillators, immersed in a common thermal bath and study the dynamics of their mutual quantum correlations in the thermodynamic, large-N limit. We
Dissipative entanglement of quantum spin fluctuations
We consider two non-interacting infinite quantum spin chains immersed in a common thermal environment and undergoing a local dissipative dynamics of Lindblad type. We study the time evolution of
Macroscopically Nonlocal Quantum Correlations.
TLDR
It is found that the Hilbert space structure of quantum theory can be preserved in the macroscopic limit, and this leads directly to a Bell violation for coarse-grained collective measurements, thus breaking the principle of Macroscopic locality.
Quantum fluctuations and correlations in open quantum Dicke models
In the vicinity of ground-state phase transitions quantum correlations can display non-analytic behavior and critical scaling. This signature of emergent collective effects has been widely
Thermodynamics of Mesoscopic Quantum Systems: from a single qubit to light harvesting complexes
Over the past few years, the exploration of mesoscopic quantum systems progressed drastically with experiments one could not imagine twenty years ago. New measurements, such as the detection of
Dynamical Phases and Quantum Correlations in an Emitter-Waveguide System with Feedback.
TLDR
This study corroborates the potential of integrated emitter-waveguide systems-which feature highly controllable photon emission channels-for the exploration of collective quantum phenomena and the generation of resources, such as squeezed states, for quantum enhanced metrology.

Entanglement of mesoscopic systems
The entanglement of clouds of N=10{sup 11} atoms recently experimentally verified is expressed in terms of the fluctuation algebra introduced by [P. Goderis, A. Verbeure, and P. Vets, Commun. Phys.
Environment induced entanglement in Markovian dissipative dynamics.
We show that two, noninteracting two-level systems, immersed in a common bath, can become mutually entangled when evolving according to a Markovian, completely positive reduced dynamics.
Entanglement generated by dissipation and steady state entanglement of two macroscopic objects.
TLDR
An experiment where dissipation continuously generates entanglement between two macroscopic objects is reported on, achieved by engineering the dissipation using laser and magnetic fields and leading to robust event-readyEntanglement maintained for 0.04 s at room temperature.
Dynamics of fluctuations for quantum lattice systems
For short range interactions and forL1-space clustering states it is proved that there exists a bonafide time evolution on the set of normal fluctuations. This dynamics is applied to derive the
Separability for lattice systems at high temperature
Equilibrium states of infinite extended lattice systems at high temperature are studied with respect to their entanglement. Two notions of separability are offered. They coincide for finite systems

We review the standard treatment of open quantum systems in relation to quantum entanglement, analyzing, in particular, the behavior of bipartite systems immersed in the same environment. We first

We investigate the possibility of using a dissipative process to prepare a quantum system in a desired state. We derive for any multipartite pure state a dissipative process for which this state is

Abstract. We present a proof of the central limit theorem for a pair of mutually non-commuting operators in mixing quantum spin chains. The operators are not necessarily strictly local but
