Title: Reflected entropy and Markov gap in non-inertial frame


We discuss the reflected entropy and Markov gap between two modes of a free fermionic field as observed by two accelerating observers. We chose both the bipartite system described by the Bell state and the tripartite system represented by the Werner and GHZ states.  We show that reflected entropy degrades monotonically as a result of the Unruh effect, eventually reaching a non-zero minimum value in the limit of infinite acceleration. Finally, we demonstrate that the Markov gap exhibits monotonic behavior with acceleration in all three cases.
