Failure of the split property in gravity and the information paradox
@article{Raju2022FailureOT, title={Failure of the split property in gravity and the information paradox}, author={S. Raju}, journal={Classical and Quantum Gravity}, year={2022}, volume={39} }
In an ordinary quantum field theory, the ‘split property’ implies that the state of the system can be specified independently on a bounded subregion of a Cauchy slice and its complement. This property does not hold for theories of gravity, where observables near the boundary of the Cauchy slice uniquely fix the state on the entire slice. The original formulation of the information paradox explicitly assumed the split property and we follow this assumption to isolate the precise error in Hawking…
