Description

In this talk, we will explore the dynamics of entanglement entropy and entanglement islands within a two-sided Reissner-Nordström black hole placed in a cavity bounded by a reflecting wall. This setup alters the dynamics of entanglement entropy, causing it to saturate at a value that is potentially lower than the thermodynamic entropy of the black hole, which contradicts the Page curve paradigm. A key finding is the temporary disappearance of the entanglement island, known as the "blinking island" effect, which periodically re-establishes the information paradox. We will discuss and compare these entanglement behaviors with the thermodynamic stability of the black hole.
