- Title: Quantum signatures of black hole mass superpositions
- Authors: Joshua Foo, Cemile Senem Arabaci, Magdalena Zych, Robert B. Mann
- Abstract summary: We apply our approach to analyze the dynamics of a detector in a spacetime generated by a BTZ black hole in a superposition of masses.
We find that the detector exhibits signatures of quantum-gravitational effects corroborating Bekenstein's seminal conjecture concerning the quantized mass spectrum of black holes in quantum gravity.

- Abstract: We present a new operational framework for studying ``superpositions of
spacetimes'', which are of fundamental interest in the development of a theory
of quantum gravity. Our approach capitalizes on nonlocal correlations in curved
spacetime quantum field theory, allowing us to formulate a metric for spacetime
superpositions as well as characterizing the coupling of particle detectors to
a quantum field. We apply our approach to analyze the dynamics of a detector
(using the Unruh-deWitt model) in a spacetime generated by a BTZ black hole in
a superposition of masses. We find that the detector exhibits signatures of
quantum-gravitational effects corroborating and extending Bekenstein's seminal
conjecture concerning the quantized mass spectrum of black holes in quantum
gravity. Crucially, this result follows directly from the approach, without any
additional assumptions about the black hole mass properties.

We find that this setup, built with massive mesoscopic particles, can potentially reveal the $t3$ gravitational phase term and thus, the BMV effect.
