ÌáÒª (Abstract)£º

In this talk, we will introduce the 4-dimensional loop quantum black holes with a cosmological constant. Compared to the classical dS (AdS) spacetime, the LQG correction sets an upper bound on the cosmological constant. The thermodynamic properties of black holes have also been discussed. We interestingly found that the temperature, the entropy as well as the heat capacity exhibit some interesting changes under quantum correction.
