Description
In this study, we examine the dynamics of entanglement entropy and entanglement islands within a two-sided extension of the Schwarzschild black hole enclosed in a cavity. By introducing a reflecting boundary in the eternal black hole exteriors, we effectively regulate the infrared modes of Hawking radiation, leading to the saturation of entanglement entropy at a constant value. Notably, this saturation value can be lower than the thermodynamic entropy of the black hole, thereby not conforming to the Page curve formulation of the information paradox. We find a universal effect induced by the presence of a boundary, which we call “blinking island” — for some time the entanglement island inevitably disappears, thus leading to a non-unitary evolution.
