Query: Emergent Schwarzschild and Reissner-Nordstrom black holes in 4D: An
  effective curvature sourced by a B2-field on a D4-brane   We obtain a Schwarzschild and a Reissner-Nordstrom emergent black holes, by
exploring the torsion dynamics in a generalized curvature formulation,
underlying an effective D4-brane on S1. It is shown that a constant effective
metric, sourced by a background fluctuation in B2-potential, on a D3-brane
receives a dynamical quantum correction in presence of an electric charge.
