Black Hole Entanglement Entropy from Cosmic Microwave Background
Comments: 28 pages, 2 figures

We study the entanglement entropy in the presence of cosmic microwave background contrast in the presence of background variations which are sensitive to the temperature and gravitational waves propagating in the black hole horizon. The dependence of entanglement entropy on the cosmic microwave background contrast is investigated. We show that the entanglement entropy is proportional to the entanglement entropy in the presence of cosmic microwave background contrast, and that the entanglement entropy is sensitive to the constants of the cosmic microwave background contrast. The entanglement entropy can be solved by the integration rule and the corresponding entanglement entropy can be calculated analytically. We calculate the entanglement entropy in the presence of cosmic microwave background contrast and find that the entanglement entropy is proportional to the entanglement entropy in the presence of cosmic microwave background contrast.
