We consider a class of Einstein-Maxwell-dilaton theories in general dimensions and construct both static and dynamic charged black holes. We adopt the reverse engineering procedure and make a specific ansatz for the scalar field and then derive the necessary scalar potential and the non-minimal coupling function between the scalar and the Maxwell field. The resulting static black holes contain mass and electric charge as integration constants. We find that some of the static solutions can be promoted to become dynamical ones in the Eddington-Finkelstein-like coordinates. The collapse solutions describe the evolution from a smaller charged black hole to a larger black hole state, driven by the scalar field.

  1. Phase Transition and Critical Phenomena of Charged Einstein-Maxwell-Scalar Black Holes

    gr-qc 2025-05 conditional novelty 5.0 of 10

    Charged EMs black holes show van der Waals-type phase transitions with mean-field critical exponents, and the phase transition disappears above a threshold scalar charge.
