Anomalous behavior of a scalar particle in a globally regular space-time of a Schwarzschild black hole
The authors solve the Klein-Gordon equation in curved space-time and find the exact solution in the interior of a Schwarzschild black hole. The probability distribution of the corresponding scalar particle is computed numerically and is shown to have a peculiar behaviour in the central region of the black hole and in the interior neighbourhood of the event horizon. The physical significance of the anomaly is not yet clear.
