  We explore whether acceleration assists entanglement harvesting for a pair of
uniformly accelerated detectors in three different acceleration scenarios,
i.e., parallel, anti-parallel and mutually perpendicular acceleration, both in
the sense of the entanglement harvested and harvesting-achievable separation
between the two detectors. Within the framework of entanglement harvesting
protocols and the Unruh-DeWitt model of detectors locally interacting with
massless scalar fields via a Gaussian switching function with an interaction
duration parameter, we find that, in the sense of the entanglement harvested,
acceleration is a mixed blessing insofar as it increases the harvested
entanglement for a large detector energy gap relative to the interaction
duration parameter, whilst inhibiting the entanglement harvested for a small
energy gap. Regarding the harvesting-achievable separation range between the
detectors, we further find that for very small acceleration and large energy
gap, both relative to the duration parameter, acceleration-assisted enhancement
can happen in all three acceleration scenarios. This is in sharp contrast to
what was argued previously: that the harvesting-achievable range can be
enhanced only for anti-parallel acceleration. However, for a not too small
acceleration relative to the duration parameter and an energy gap larger than
the acceleration, we find that only detectors in parallel acceleration possess
a harvesting-achievable range larger than those at rest.
