Back-action from Unruh-DeWitt detectors produces energy fluxes that exactly account for detector transitions due to the Unruh effect, including negative energy density regions near the Rindler horizon and in the far future for ground-state accelerated detectors.
Multiple Unruh-DeWitt detectors harvest more vacuum entanglement when arranged in specific configurations, with harvested negativity scaling linearly in linear chains.
