Abstract:We consider two Unruh-DeWitt detectors interacting with a massless, minimally coupled scalar field in a (1+1) dimensional Reissner-Nordstrom black hole spacetime. In particular, one of the detectors, corresponding to Alice, is moving along an outgoing null trajectory. While the other detector carried by Bob is static. With this set-up, we investigate the entangling condition and the measure of the entanglement, concurrence, in the nonextremal and extremal scenarios. Our observations suggest, as expected, a qua… Show more
