Holographic time-dependent entanglement entropy in p-brane gas geometries

We study the time evolution of entanglement entropy in expanding universes with various matters. To describe holographically, we take into account a braneworld moving an asymptotic AdS space involving uniform $p$-brane gas. In model, observer living detects bulk motion as universe. show that increases by volume law early and area late time. further consider cosmological horizon, which is border visible invisible universe, then investigate time-dependent quantum between them across horizon.
