Information paradox and island of covariant black holes in LQG
Yongbin Du, Jia-Rui Sun, Xiangdong Zhang
We study information paradox of four dimensional covariant black holes inspired by loop quantum gravity (LQG) with two well motivated solutions. We first prepare the spacetime in t…

Island of acoustic black hole in Schwarzschild spacetime
Yu-Ye Cheng, Jia-Rui Sun
We study an analogue information paradox in acoustic black holes which are emerged from the superfluid surrounding a Schwarzschild black hole. The resulting acoustic black hole con…
