trailAlternative derivations of Hawking radiation avoid appealing to trans-Planckian frequencies.
The derivation of Hawking radiation depends on unknown trans-Planckian physics.
Quantum field theory in curved spacetime predicts thermal radiation from black hole event horizons.
Derivation routes without mode tracing· for
Tunneling, Euclidean, and anomaly-based derivations of Hawking radiation do not trace modes through the near-horizon exponential blueshift.
atomic
Independent theoretical derivations converge on the same black hole temperature.
atomic
Explicit-cutoff derivations· for
Modified trans-Planckian dispersion relations in black-hole models preserve the thermal spectrum at the Hawking temperature.
atomic
Hidden trans-Planckian assumptions· against
Alternative derivations of Hawking radiation implicitly assume the quantum state is regular across the horizon at arbitrarily short distances.
Tunneling, Euclidean, and anomaly-based derivations of Hawking radiation impose regularity of the quantum state at the horizon.
The Hawking spectrum can be derived assuming the quantum state is regular only down to an invariant Planck-scale cutoff.
The Hawking spectrum's insensitivity to modified dispersion holds only under conditions such as a free-falling vacuum and adiabatic evolution.
assumed
Hawking's original derivation traces outgoing modes back to frequencies far above the Planck scale.
