Quantum-classical correspondence of non-Hermitian spin-orbit coupled bosonic junction [4.934387267206206]
We show that near the symmetry-breaking phase transition point, the correspondence between classical (mean-field) and quantum dynamics is more likely to break down. In both the mean-field and many-particle models, the SOC effects can greatly promote the synchronous periodic oscillations between the spin-up and spin-down components.

Relaxing towards generalized one-body Boltzmann states [8.492309089637512]
Isolated quantum systems follow the reversible unitary evolution. We study the local relaxation process in an isolated chain consisting of emphN three level systems.

Measuring the Evolution of Entanglement in Compton Scattering [101.11630543545151]
The behavior of quantum entanglement during scattering is identical to the behavior of initially classically correlated photons up to a constant factor equal to two. Our dedicated experiment with photons confirms these results and explains the "Puzzle of Decoherence" observed recently.

Inherent quantum resources in stationary spin chains [0.0]
We show that many-body Bell correlations are inherently present in the eigenstates of a variety of spin-1/2 chains. In particular, we show that the eigenstates and thermal states of the collective Lipkin-Meshkov-Glick model possess many-body Bell correlations.

Chaos and quantization of the three-particle generic Fermi-Pasta-Ulam-Tsingou model I: Density of states and spectral statistics [5.387047563972287]
We study the mixed-type classical dynamics of the three-particle Fermi-Pasta-Ulam-Tsingou (FPUT) model in relationship with its quantum counterpart.

Quantifying total correlations in quantum systems through the Pearson correlation coefficient [0.23999111269325263]
We show that a quantum state can be correlated in either a classical or a quantum way, i.e., the two cases are mutually exclusive.<n>We also illustrate that, at least for the case of two-qubit systems, the distribution of the correlations among certain locally incompatible pairs of observables provides insight in regards to whether a system contains classical or quantum correlations.

Optical and atomic decoherence in entangled atomic ensembles generated by quantum nondemolition measurements [5.301892337432412]
We study the effects of decoherence in the form of optical phase diffusion, photon loss and gain, and atomic dephasing in entangled atomic ensembles. For the optical decoherence channels, we use the technique of integration within ordered operators (IWOP) to obtain the Kraus operators that describe the decoherence.

Almost synchronous quantum correlations [7.716156977428555]
The study of quantum correlation sets was initiated by Tsirelson in the 1980s and originally motivated by questions in the foundations of quantum mechanics. Synchronous correlation sets introduced in [Paulsen et. al, JFA 2016] are a subclass of correlations that has proven particularly useful to study and arises naturally in applications.

Dynamical pairwise entanglement and two-point correlations in the three-ligand spin-star structure [0.0]
We consider the three-ligand spin-star structure through homogeneous Heisenberg interactions (XXX-3LSSS) It is shown that the time evolution of the central qubit "one-particle" state results in the generation of quantum W states at periodical time instants.

Maximally entangled correlation sets [6.09170287691728]
We study the set of quantum correlations generated by actions on maximally entangled states. As a consequence, we show that these correlations are dense in the set of synchronous quantum correlations.

Quantum correlations between separated particles [0.0]
Long-range quantum correlations between particles are usually formulated by assuming the persistence of an entangled state after the particles have spearated.<n>This approach is re-examined based upon studying the correlations present in a pair of EPR spins.
