摘要
In this paper, we investigate the extended uncertainty principle (EUP) effects on the Van der Waals (VdW) black holes whose thermal quantities mimic the VdW liquid. We find that the considered formalism imposes an upper bound on the event horizon radius. Thus, the mass, Hawking temperature, and heat capacity become physically meaningful within a certain range of event horizon radii. At a large event horizon radius, the black hole has a remnant. We observe that for a given set of parameters, the VdW black hole can be completely unstable for all horizon radii, while for another set of parameters, it can be unstable or stable depending on the horizon radius.
