Thermodynamics and mechanical laws of causal-diamond horizons
Carlos R. Ordóñez, Gustavo Valdivia-Mera
We develop a unified thermodynamic and mechanical framework for causal-diamond horizons in Minkowski spacetime. Euclidean regularity fixes the temperature , where …
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…
Path integral derivation of the thermofield double state in causal diamonds
Abhijit Chakraborty, Carlos R. Ordóñez, Gustavo Valdivia-Mera
In this article, we adopt the framework developed by R. Laflamme in \textit{Physica A}, \textbf{158}, pp. 58-63 (1989) to analyze the path integral of a massless -- conformally inv…
Anomalous changing of geodesics in hairy black holes
Weyner Ccuiro, David Choque, Gustavo Valdivia-Mera
We study the motion of test particles and the propagation of light around neutral hairy black holes under the influence of a self-interacting real scalar field minimally coupled to…
On the Unruh effect and the thermofield double state
Gustavo Valdivia-Mera
The purpose of this review is to provide a pedagogical development of the Unruh effect and the thermofield double state. In Section 2, we construct Rindler spacetime and analyze th…
