  We continue our recent endeavor in which a time-dependent black hole solution
of a one-loop quantum-corrected Einstein-scalar system was obtained and its
near-horizon behavior was analyzed. The energy analysis led to a
trans-Planckian scaling behavior near the event horizon. In the present work
the analysis is extended to a rotating black hole solution of an
Einstein-Maxwell-scalar system with a Higgs potential. Although the analysis
becomes much more complex compared to that of the previous, we observe the same
basic features, including the quantum-gravitational trans-Planckian energy near
the horizon.
