Title: Correlation harvesting between particles in uniform motion
Abstract: Correlation harvesting is a phenomenon where two particles can become entangled via local interactions with a quantum field. The Wightman function describing this situation for the case of uniformly accelerated particle detectors can be characterized by a master equation, where different types of motion (linear, cusped, catenary and circular) arise from tuning a single parameter in the equation. We investigate the correlation harvesting protocol for this generalized case of uniformly accelerated particles. We investigated both the case of stationary (time-translationally invariant Wightman function) and non-stationary configurations and compared the amount of harvestable classical & quantum correlations in each case. Remarkably, we found that although we cannot harvest entanglement from causally separated uniformly accelerated detectors, we can still achieve "genuine" (i.e. non-communication-assisted) entanglement harvesting in regions where the detectors are in causal contact.
