Quantum correlation and origin of Hawking radiation for mass-superposed BTZ black holes

Year: 2025

Type: article

Abstract: We investigate the mass superposition of Bañados-Teitelboim-Zanelli (BTZ) black holes using the velocity correlation function. Interestingly, the quantum signatures of BTZ black hole mass superposition can be revealed by the velocity correlation peaks. Additionally, different mass superpositions for the same mass ratio can be distinguished, a phenomenon not previously documented. We also find that the correlation function method can pinpoint the location where Hawking radiations are generated, even for mass-superposed BTZ black holes. This supports the concept of a quantum atmosphere as the origin locus of Hawking radiation, even in quantum-superposed spacetime.
