Effects of a cloud of strings on the extended phase space of Einstein-Gauss-Bonnet AdS black holes
In this paper we study the thermodynamics of Einstein-Gauss-Bonnet (EGB)-AdS
black holes minimally coupled to a cloud of strings in an extended phase space
where the cosmological constant is treated as pressure of the black holes and
its conjugate variable is the thermodynamical volume of the black holes. To
investigate the analogy between EGB black holes surrounded by a cloud of
strings and liquid-gas system we derive the analytical solutions of the
critical points and probe the effects of a cloud of strings on
criticality. There is obtained resemblance between "small black hole/large
black hole" (SBH/LBH) phase transition and the liquid-gas phase transition. We
see that impact of a cloud of strings can bring Van der Waals-like behavior, in
absence of the Gauss-Bonnet (GB) counterpart. In the other words, in the EGB
black hole with and when it is surrounded by a cloud of strings
the Hawking-Page phase transition would be disappeared and SBH/LBH phase
transition recovers. Also there is not happened Joule-Thomson effect.Comment: 18 pages, 4 figur
