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 …

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…
