Entanglement system, Casimir energy and black hole

TL;DR

This paper explores the relationship between entanglement systems, Casimir energy, and black holes, showing that Casimir energy better approximates black hole energy and that entanglement systems mimic black hole behavior under gravity.

Contribution

It demonstrates that Casimir energy aligns more closely with black hole energy than entanglement energy and shows how entanglement systems can behave like black holes when gravitational effects are considered.

Findings

Casimir energy resembles black hole energy more than entanglement energy.

Entanglement systems satisfy the Bekenstein entropy bound.

Including gravity makes entanglement systems behave like black holes.

Abstract

We investigate the connection between the entanglement system in Minkowski spacetime and the black hole using the scaling analysis. Here we show that the entanglement system satisfies the Bekenstein entropy bound. Even though the entropies of two systems are the same form, the entanglement energy is different from the black hole energy. Introducing the Casimir energy of the vacuum energy fluctuations rather than the entanglement energy, it shows a feature of the black hole energy. Hence the Casimir energy is more close to the black hole than the entanglement energy. Finally, we find that the entanglement system behaves like the black hole if the gravitational effects are included properly.
