abstract
We explore the entanglement of the vacuum of a relativistic field by letting a pair of causally disconnected probes interact with the field. We find that, even when the probes are initially non-entangled, they can wind up to a final entangled state. This shows that entanglement persists between disconnected regions in the vacuum. However the probe entanglement, unlike correlations, vanishes once the regions become sufficiently separated. The relation between entropy, correlations and entanglement is discussed.

Entanglement between accelerated probes in de Sitter spacetime varies independently with acceleration and curvature depending on detector motion configurations, unlike the single-probe effective-acceleration mapping.
The reduced states of static UDW detectors coupled to a scalar field in alpha-vacua are derived analytically, revealing distinct behaviors of entanglement harvesting for time-like versus space-like separations and superhorizon suppression of quantum discord.
Cavity-mediated interaction plus self-energy renormalization in (1+2) Dirac QED produces enhanced momentum-resolved entanglement entropy and stationary Bell-like states when coherence time exceeds interlayer photon propagation time.
