Thermodynamic modifications to Bardeen black holes surrounded by quintessence based on the new higher order GUP

Bo-Li Liu, Yu Zhang, Qi-Quan Li +1

In this article, the thermodynamic properties of Bardeen black holes surrounded by quintessence are investigated in the framework of a new higher order GUP. The modified Hawking te…

Strong gravitational lensing in a Kerr black hole within Quantum Einstein Gravity

Chen-Hao Xie, Yu Zhang, Bo-Li Liu +2

The detailed study of the strong gravitational lensing of a Kerr black hole within Quantum Einstein Gravity (QEG) is performed. We calculate the photon sphere, the deflection angle…
