Hawking Radiation as Tunneling
read the original abstract
We present a short and direct derivation of Hawking radiation as a tunneling process, based on particles in a dynamical geometry. The imaginary part of the action for the classically forbidden process is related to the Boltzmann factor for emission at the Hawking temperature. Because the derivation respects conservation laws, the exact spectrum is not precisely thermal. We compare and contrast the problem of spontaneous emission of charged particles from a charged conductor.

Hawking radiation with dispersion: reconciling the Bogoliubov and tunneling approaches
For even convex polynomially bounded dispersion relations, an effective horizon controls the outgoing modes so that Bogoliubov coefficients agree with the tunneling result and the emission spectrum deviates from exact...

Eikonal quasinormal modes, greybody factors and shadow of charged accelerating black holes
Eikonal quasinormal modes for accelerating black holes are determined by the angular velocity and Lyapunov exponent of null geodesics, yielding universal greybody factors for any spin and explicit shadow radii that re...

Hawking Radiation meets the Double Copy
Bogoliubov coefficients from scattering a scalar in a collapsing EM background (single copy of Vaidya) match ray-tracing results and connect to Hawking radiation through the double copy.

Tunnelling across a trapped region and out of a black hole
Quantum tunneling probability for particles escaping a 2D non-singular black hole is non-vanishing and depends only on the surface gravities of the inner and outer horizons.
