Reflected entropy in random tensor networks

Understand

In holographic theories, the reflected entropy has been shown to be dual to the area of the entanglement wedge cross section.

• We study the same problem in random tensor networks demonstrating an equivalent duality.
• For a single random tensor we analyze the important non-perturbative effects that smooth out the discontinuity in the reflected entropy across the Page phase transition.
• By summing over all such effects, we obtain the reflected entanglement spectrum analytically, which agrees well with numerical studies.
