Evaporation and fate of covariant quantum black holes
Li-Shuai Wang, Xiangdong Zhang
A growing number of phenomena and theoretical problems indicate that quantum gravity theory is necessary. In this paper, we investigate the evaporation of covariant quantum BHs for…

Quantum Oppenheimer-Snyder primordial black holes as all the dark matter
Li-Shuai Wang, Xiangdong Zhang
Primordial black holes (PBHs) are widely considered as candidates for dark matter in many recent studies, and they are often modeled as Schwarzschild or Kerr black holes (BHs), whi…

Primordial black holes and scalar induced gravitational waves from sound speed resonance in non-minimal derivative coupling inflation model
Li-Shuai Wang, Qiong-Tao Xie, Li-Yang Chen
We investigate an inflationary model with a non-minimal derivative coupling, where the coupling function contains both constant and periodic components. On large scales, the model…
