abstract

We develop the idea that, in quantum gravity where the horizon fluctuates, a black hole should have a discrete mass spectrum with concomitant line emission. Simple arguments fix the spacing of the lines, which should be broad but unblended. Assuming uniformity of the matrix elements for quantum transitions between near levels, we work out the probabilities for the emission of a specified series of quanta and the intensities of the spectral lines. The thermal character of the radiation is entirely due to the degeneracy of the levels, the same degeneracy that becomes manifest as black hole entropy. One prediction is that there should be no lines with wavelength of order the black hole size or larger. This makes it possible to test quantum gravity with black holes well above Planck scale.

  • Emergent Hawking Radiation and Quantum Sensing in a Quenched Chiral Spin Chain cond-mat.stat-mech · 2026-02-04 · unverdicted · none · ref 73 · internal anchor

    A quenched chiral spin chain produces analog Hawking radiation with non-Planckian spectrum but Poissonian statistics, detectable by a weakly coupled qubit sensor that reveals the horizon-induced temperature.

  • Testing the nature of dark compact objects: a status report gr-qc · 2019-04-10 · accept · none · ref 42

    Current and future observations can test whether dark compact objects are Kerr black holes or exotic alternatives, with null results strengthening the black hole paradigm.
