An atom falling freely into a Kerr black hole in a Boulware-like vacuum is shown to emit radiation with a Planck spectrum at the Hawking temperature. For a cloud of falling atoms with random initial times, the radiation is thermal. The existence of this radiation is due to the acceleration of the vacuum field modes with respect to the falling atom. Its properties can be traced to the dominant role of conformal quantum mechanics (CQM) in the neighborhood of the event horizon. We display this effect for a scalar field, though the acceleration radiation has a universal conformal behavior that is exhibited by all fields in the background of generic black holes.

  1. Ringdown modulation of acceleration radiation in the Schwarzschild background

    gr-qc 2025-11 reject novelty 5.0 of 10

    Near a Schwarzschild horizon, a quadrupolar quasinormal ringdown is claimed to modulate the detector detailed-balance exponent by a decaying sinusoid at the QNM frequency, at first order in the perturbation amplitude.

  2. Integrals of motion on extremals of the equation Euler-Lagrange

    physics.class-ph 2025-08 unverdicted novelty 4.0 of 10

    The paper claims that Wronskian determinants of closed first-order ODE systems serve as integrals of motion on Euler-Lagrange extremals, constructed via the Jacobi equation.
