Optimization of entanglement harvesting with arbitrary temporal profiles: the limit of second order perturbation theory
A Hermite-expansion method optimizes the temporal switching profiles of Unruh-DeWitt detectors and claims order-of-magnitude improvements in vacuum entanglement harvesting, with the largest gains occurring outside the validity of the perturbative calculation used.
