Abstract:
We explore the reflected entropy and the Markov gap between two modes
of a free fermionic field as observed by accelerating observers. This is
done for both bipartite system which is described by Bell state and
tripartite systems which are represented by Werner and
Greenberger–Horne–Zeilinger states. The reflected entropy degrades
monotonically as a result of the Unruh effect, eventually reaching a
non-zero minimum value in the limit of infinite acceleration. Furthermore,
we show that the Markov gap exhibits monotonic behavior with regard to
acceleration in all three cases. Finally, we confirm that the reflected
entropy for our system does reduce under the partial tracing of the degrees
of freedom for our states.
