Area-Information Trade-Offs in Acceleration Radiation from Atoms Falling into Black Holes

Yusef Maleki, Gustavo Valdivia-Mera, Carlos R. Ordonez +2

We develop a geometric theory of information processing in the Horizon-brightened acceleration radiation (HBAR) channel, in which the radiative horizon-area change provides an entr…

Acceleration radiation and HBAR thermodynamics for atoms falling into a BTZ black hole: A CQM quantum-optics approach

H. E. Camblong, A. Chakraborty, C. R. Ordóñez +3

Atoms falling freely into a Bañados-Teitelboim-Zanelli (BTZ) black hole in a Boulware-like vacuum are shown to emit radiation with a Planck spectrum at the Hawking temperature $T_{…

The Helical SYK Model and Emergent Infrared Integrability

Gustavo Valdivia-Mera, Bhavay Tyagi, Eric R. Bittner +1

We construct a helical generalization of the Sachdev-Ye-Kitaev (SYK) model in dimensions, built from left- and right-moving Majorana fermions with local quartic interactions…

Thermal nature of the causal diamond horizon: A hidden property of the inertial propagator

Nada Eissa, Carlos R. Ordóñez, Gustavo Valdivia-Mera

Inspired by the novel idea proposed by T.~Padmanabhan in \textit{Phys.\ Rev.\ D 100, 045024 (2019)}, we develop a method to uncover the hidden thermal properties of the inertial Fe…

Horizon brightened acceleration radiation entropy in causal diamond geometry: A near-horizon perspective

Nada Eissa, Carlos R. Ordóñez, Gustavo Valdivia-Mera

In this article, we extend the horizon brightened acceleration radiation (HBAR) framework, originally introduced by Marlan Scully et al. in Proceedings of the National Academy of S…
