Holographic entanglement entropy of deSitter braneworld with Lovelock
Kouki Kushihara, Keisuke Izumi, Tetsuya Shiromizu
TL;DR
This paper demonstrates that in a deSitter braneworld model with Lovelock terms, the holographic entanglement entropy matches the deSitter entropy computed via Euclidean action, confirming a deep connection between these concepts.
Contribution
It shows the equivalence of holographic entanglement entropy and Euclidean deSitter entropy in a Lovelock gravity braneworld setting, extending previous results to more complex gravity theories.
Findings
Holographic entanglement entropy equals Euclidean deSitter entropy in the model.
Lovelock terms do not break the entropy equivalence.
The result supports the holographic principle in higher curvature gravity theories.
Abstract
We examine the deSitter entropy in the braneworld model with the Gauss-Bonnet/Lovelock terms. Then, we can see that the deSitter entropy computed through the Euclidean action exactly coincides with the holographic entanglement entropy.
