Abstract

In this work we extend previous work on the evolution of a primordial black hole PBH to address the presence of a dark energy component with a supernegative equation of state as a background investigating the competition between the radiation accretion the Hawking evaporation and the phantom accretion the latter two causing a decrease on black hole mass It is found that there is an instant during the matterdominated era after which the radiation accretion becomes negligible compared to the phantom accretion The Hawking evaporation may become important again depending on a mass threshold The evaporation of PBHs is quite modified at late times by these effects but only if the generalized second law of thermodynamics is violated
