(2022) 085007}, we have explored the event of acceleration radiation for an
atom freely falling into the event horizon of a quantum-corrected Schwarzschild
black hole. We want to explore the acceleration-radiation when the atom is
freely falling into the event horizon of a charged quantum-corrected black
hole. We consider the quantum effects of the electromagnetic field along with
the gravitational field in an asymptotic safety regime. Introducing the quantum
improved Reisner-Nordstr\"{o}m metric, we have calculated the excitation
probability of a two-level atom freely falling into the event horizon of
quantum improved charged black hole. Recently, in the case of the braneworld
black hole (where the tidal charge has the same dimension as the square of the
charge of a Reissner-Nordstr\"{o}m black hole in natural units), we have
observed from the form of the transition probability that the temperature will
have no contribution in the first order of the tidal charge. We observe that
for a quantum corrected Reissner-Nordstr\"{o}m black hole, there is a
second-order contribution in the charge parameter in the temperature that can
be read off from the transition probability. Next, we calculate the HBAR
entropy in this thought experiment and show that this entropy has a leading
order Bekenstein-Hawking entropy term along with some higher order correction
terms involving logarithmic as well as fractional terms of the black hole area
due to infalling photons. We have finally investigated the validity of Wien's
displacement law and compared the critical value of the field wavelength with
the general Schwarzschild black hole and its corresponding quantum-corrected
case.
