Entanglement-based measure of non-Makovianity in relativistic frame

We investigate the entanglement-based measure of non-Markovianity of a free Dirac field in a non-inertial frame. We find that the acceleration parameter speeds up the degradation of non-Markovianity from the perspective of entanglement of formation for both amplitude and phase damping environment. O...

Description
Summary:We investigate the entanglement-based measure of non-Markovianity of a free Dirac field in a non-inertial frame. We find that the acceleration parameter speeds up the degradation of non-Markovianity from the perspective of entanglement of formation for both amplitude and phase damping environment. On the other hand, the accessible information increases with acceleration show a temporary increase and decrease with finite scaled-time interval, approach to unity in the infinite scaled-time limit for amplitude damping environment in the non-Markovian regime. However, for the phase damping environment, the accessible information temporarily increases and decreases with finite scaled-time intervals, achieving a uniform value (less than one) in the non-Markovian regime. For a given acceleration, the entanglement of formation (accessible information) monotonically decreases (increases) in scaled-time for both amplitude and phase damping channels in the Markovian regime. •We investigate the entanglement-based measure of non-Markovianity of a free Dirac field in a non-inertial frame.•The acceleration parameter speeds up the degradation of non-Markovianity in the amplitude and phase damped system.•The accessible information increases with acceleration show a temporary increase and decrease with finite scaled-time interval.
