| contents | We construct black hole geometries coexisting with anisotropic matter in (anti)-de Sitter spacetime. We specifically focus on the black hole phase transitions that occur in anti-de Sitter spacetime and analyze the effects of the incorporated matter fields. Its local stability is examined by evaluating the heat capacity, while global stability is investigated in greater detail through phase transition analysis. The black hole system coexisting with the matter field allows for a phase transition from a small black hole to a large black hole. This demonstrates that the constructed geometry with the matter field would resemble that of the Reissner-Nordström black hole. We examine null geodesics, particularly unstable homoclinic orbits, which allow us to obtain Lyapunov exponents that characterize sensitivity to initial conditions. Finally, we analyze the relationship between the different black hole phases and the behavior of these Lyapunov exponents. |
