This lightning talk explores how freely falling two-level atoms emit acceleration radiation near the horizons of Bardeen regular black holes. The authors combine quantum optics with conformal quantum mechanics to show that atoms falling toward these black holes experience a Planckian spectrum of radiation controlled by the Bardeen Hawking temperature. This work reveals how the regular core parameter modulates radiation properties and offers a quantum-optical diagnostic tool for probing black hole thermodynamics without singularities.
