Bosonic and Fermionic love number of static acoustic black hole
Yongbin Du, Xiangdong Zhang
We compute static () tilde Love numbers for scalar () and Dirac () perturbations of static acoustic black holes (ABHs) in (3+1) and (2+1) dimensions respectively…

Solar-system experimental constraints on nonlocal gravity
Yunlong Liu, Yongbin Du
In this work, we study the constraints on the characteristic parameters of the Deser-Woodard nonlocal gravity model in a static and spherically symmetric background, using…

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…
