Description

In this work, we present the thermodynamic
study of amodel that considers the black hole as a condensate
of gravitons. In this model, the spacetime is not asymptotically
flat because of a topological defect that introduces an
angle deficit in the spacetime like in Global Monopole solutions.
We have obtained a correction to the Hawking temperature
plus a negative pressure associated with the black
hole of mass M. In this way, the graviton condensate, which
is assumed to be at the critical point defined by the condition
μch = 0, has well-defined thermodynamic quantities
P, V, Th, S, and U as any other Bose–Einstein condensate
(BEC). In addition, we present a formal equivalence between
the Letelier spacetime and the line element that describes
the graviton condensate. We also discuss the Kiselev black
hole, which can parametrize the most well-known spherically
symmetric black holes. Finally, we present a new metric,
which we will call the BEC–Kiselev solution, that allows
us to extend the graviton condensate to the case of solutions
with different matter contents.
