Notes on islands in asymptotically flat 2d dilaton black holes
Takanori Anegawa, Norihiro Iizuka
Abstract
A bstract We study the islands and the Page curve in the 1+1-dimensional eternal dilaton black hole models. Without islands, the entanglement entropy of the radiation grows linearly at late time. However with an island, its growth stops at the value of almost twice of the black hole entropy. Therefore an island emerges at the late time, and the entanglement entropy of the radiation shows the Page curve.
