Abstract
This paper investigates the Page curve in warped anti-de Sitter black holes using the “quantum extremal surface” prescription. The findings reveal that in the absence of an island, the entanglement entropy of Hawking radiation grows proportionally with time and becomes divergent at later times. However, when considering the island’s emergence, which extends slightly beyond the event horizon, the growth of the entanglement entropy of Hawking radiation comes to a constant value. Eventually, the constant value is precisely twice the Bekenstein–Hawking entropy. We have also discussed the Page time and the scrambling time.
