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…

Dynamical properties of Bianchi-I spacetimes in gravity
Saikat Chakraborty, Kazuharu Bamba, Alberto Saa
We present a dynamical analysis in terms of new expansion-normalized variables for homogeneous and anisotropic Bianchi-I spacetimes in gravity in the presence of anisotropic…
