• Abstract: Recently, it was suggested that the Hawking radiation may originate not at the event horizon but in the quantum region outside of it, known as the quantum atmosphere. The present study attempts to explore this argument further by assessing its role in shaping quantum correlations near a black hole. Herein, these are conveniently captured within the geometric measure of nonlocality, termed as the measurement-induced nonlocality, and found to exhibit signatures of the atmosphere. In particular, a notable loss of correlations is observed well outside the event horizon, coinciding with the peak of particles radiation in the atmosphere region. Still, the correlations are shown to be always finite therein and to continuously scale with not only the radiation temperature but also with the horizon size. Hence, some characteristics of the atmosphere appears to be detectable at the quantum correlations level, providing novel insight and means to help verify the concept of interest.

As Hawking decoherence intensifies in the physically inaccessible and spacetime regions, the quantum correlations of Dirac fields reemerge.

• Measurement-induced nonlocality for noninertial observers near a black hole [0.0]
  In the infinite Hawking temperature limit, the physically accessible correlations does not vanish only in the fermionic case. The higher frequency modes can sustain correlations for the finite Hawking temperature. Since the MIN for the latter modes quickly diminishes, the increased frequency may be a way to maintain nonlocal correlations for the scenarios at the finite Hawking temperature.

  This work proposes a candidate model, based on the central hypothesis that all horizons are universal boundaries of coherent quantum information. The prediction is inspired by 't Hooft's algebra for black hole information that gives coherent states on horizons. Time-domain correlations are projected from Planckian jitters whose coherence scales match causal diamonds.

We show that, in addition to the Hawking effect at the sonic horizon, quantum fluctuations may result in a sizeable stationary excitation of a quasi-normal mode of the field theory.
