- Abstract: I discuss the time evolution of quantum entanglement in presence of
non-collapsing interactions. In the case of relativistic systems, the
correlation between entangled processes is defined by the equality of the
correspondent invariant intervals. As an example, the entanglement between the
products of a particle decay is revisited, leading to correlations in precise
agreement with the muon $g-2$ experimental results. The extension of such a
postulate to the curved space-time is also used to discuss the survival of
entanglement in the presence of horizons.

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.

Quasiparticles are emergent excitations of matter that underlie much of our understanding of quantum many-body systems.
We take advantage of the clean setting of homogeneous quantum gases and fast radio-frequency control to manipulate Fermi polarons.
We measure the decay rate and the quasiparticle residue of the driven polaron from the Rabi oscillations between the two internal states.

We report observation of quasiparticle pair-production and characterize quantum entanglement created by a modulational instability in an atomic superfluid.
By quenching the atomic interaction to attractive and then back to weakly repulsive, we produce correlated quasiparticles.
We observe large amplitude growth in the power spectrum and subsequent coherent oscillations in a wide spatial frequency band within our resolution limit.
