A New Approach to Black Hole Thermodynamics in General EMD-like Theories
Peng-Yu Wu, H. Lu
We consider general EMD-like theories involving arbitrary numbers of both Maxwell fields and dilatonic scalars. We study charged black holes and derive several algebraic and differ…

Schwarzschild Black Hole in Uniform Magnetic Field in Einstein-Maxwell-Dilaton Theories
Liang Ma, Peng-Yu Wu, H. Lu
We obtain the Kerr black hole in an external uniform magnetic field in the Kaluza-Klein (KK) theory via a standard solution-generating technique. Using this as our starting point,…

Exact Toda Black Holes of Rank-2 Lie Groups
H. Lu, Peng-Yu Wu, Ze-Hua Wu +1
We consider Einstein gravity coupled to two Maxwell fields and one dilatonic scalar, and construct spherically-symmetric and static black holes that are charged under both Maxwell…
