Abstract
In this work, we have investigated the phenomenon of acceleration radiation exhibited by an atom falling into a quantum corrected Schwarzschild black hole. We observe that the excitation probability of an atom with the simultaneous emission of a photon satisfies the equivalence principle when we compare it to the excitation probability of a mirror accelerating with respect to an atom. We also demonstrate the validity of the equivalence principle for a generic black hole geometry. Then we calculate the horizon brightened acceleration radiation entropy for this quantum corrected black hole geometry. We observe that the horizon brightened acceleration radiation entropy has a form identical to that of Bekenstein-Hawking black hole entropy along with universal quantum gravity corrections.
