Topological dyonic dilaton black holes in AdS spaces

摘要: We construct a new class of dyonic dilaton black hole solutions in the background Anti-de Sitter (AdS) spacetime. In order to find an analytical solution which satisfy all field equations, we should consider string case where coupling is $\alpha=1$. The asymptotic behaviour ($r\rightarrow\infty$) exactly AdS, becomes zero and metric function reduces $f(r)\rightarrow -\Lambda r^2/3$. this spacetime, horizons cosmological horizons, can be two-dimensional positive, or negative constant curvature surface. study physical properties show that depending on parameters, these describe holes with one two naked singularity. investigate thermodynamics by calculating charge, mass, temperature, entropy electric potential disclose conserved thermodynamic quantities first law thermodynamics. also analyze thermal stability conditions for have stable hole.
