Entanglement in the presence of non-perturbative gravitational waves

In this paper we study the entanglement entropy in the presence of non-perturbative gravitational waves in the vicinity of a black hole in the vicinity of a spinning electron-positron star. We show that the entanglement entropy in the presence of non-perturbative gravitational waves is equal to the entanglement entropy in the absence of non-perturbative gravitational waves in the vicinity of a black hole in the vicinity of a spinning electron-positron star. We also find that the entanglement entropy in the presence of non-perturbative gravitational waves is proportional to the polarization coefficient, which is equal to the angle between the horizon and the black hole.
