Abstract

In this work, we show that the radial solutions of the Klein-Gordon equation in an AdS spacetime composed of a black string, surrounded by both a matter distribution analogous to a string cloud and an anisotropic quintessence fluid, exhibit the occurrence of so-called dark phases, which are induced by the presence of the quintessential fluid. These dark phases are possible quantum observables for spin−0 particles located near the
black string’s event horizon.
