Near-horizon modes and self-adjoint extensions of the Schroedinger operator
A. P. Balachandran, A. R. de Queiroz, Alberto Saa
We investigate the dynamics of scalar fields in the near-horizon exterior region of a Schwarzschild black hole. We show that low-energy modes are typically long-living and might be…
