Songbai Chen, Jiliang Jing
TL;DR
This paper investigates how phantom scalar fields, characterized by negative kinetic energy, affect Hawking radiation and super-radiance in Kerr black holes, revealing enhanced emission compared to normal scalars.
Contribution
It introduces the analysis of phantom scalar fields in Kerr black holes and demonstrates their impact on radiation spectra and super-radiance phenomena.
Findings
Phantom scalar emission is enhanced relative to normal scalar fields.
Negative kinetic energy modifies greybody factors and super-radiance.
Hawking radiation spectra are significantly affected by phantom fields.
Abstract
We study the absorption probability and Hawking radiation spectra of a phantom scalar field in the Kerr black hole spacetime. We find that the presence of the negative kinetic energy terms modifies the standard results in the greybody factor, super-radiance and Hawking radiation. Comparing with the usual scalar particle, the phantom scalar emission is enhanced in the black hole spacetime.
