Abstract
Locality plays a key role in the derivation of Hawking radiation. Could relaxing the locality criterion modify Hawking radiation? We consider Hawking radiation in a general class of non local quantum field theories. This includes theories with a minimal length or UV cut-off. We prove that Hawking radiation is unmodified for these theories. Our result establishes the universality of Hawking radiation in a general class of non local theories.
Highlights
One of the most striking predictions of quantum field theory in curved spacetime is Hawking radiation - the prediction that quantum effects near the event horizons of black holes cause them to emit radiation
At the same time this result leads to the notorious black hole information loss paradox which has remained intractable despite many years of effort
It has been argued that giving up locality can modify Hawking’s result and resolve the black hole information loss paradox
Summary
Dawood Kothawala† Department of Physics, Indian Institute of Technology Madras, Chennai 600040. Locality plays a key role in the derivation of Hawking radiation. Could relaxing the locality criterion modify Hawking radiation? We consider Hawking radiation in a general class of non local quantum field theories. We prove that Hawking radiation is unmodified for these theories. Our result establishes the universality of Hawking radiation in a larger class of theories
