摘要

Considering a grand canonical ensemble,we study the phase structures and transitions of RN black holes surrounded by quintessence dark energy on two different boundary conditions,namely AdS space and a Dirichlet wall.For AdS space,under the condition of fixed temperature and potential,as the temperature increases for lower potential,the black hole undergoes a first-order phase transition,while for higher potential,no phase transition oc-curs.There are two different regions in the parameter space.For the Dirichlet wall,on which the temperature and po-tential are fixed,the state parameter of quintessence ω =-2/3 is analyzed in detail.Then,three different physically allowed regions in the parameter space of the black hole are well studied.As the temperature rises,first-order and second-order phase transitions may occur.In this case,there are nine regions in the parameter space,which is evid-ently distinct from the case of AdS space.
