Dyonic dilaton black holes

  title={Dyonic dilaton black holes},
  author={Stephen Poletti and Jason Twamley and David Wiltshire},
The properties of static spherically symmetric black holes, which are both electrically and magnetically charged, and which are coupled to the dilaton in the presence of a cosmological constant, , are considered. It is shown that apart from the Reissner--Nordstrom--de Sitter solution with constant dilaton, such solutions do not exist if (in arbitrary spacetime dimension ). However, asymptotically anti-de Sitter dyonic black-hole solutions with a non-trivial dilaton do exist if . Both these… CONTINUE READING
