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
The paper demonstrates that atoms freely falling into a (2+1)-dimensional BTZ black hole emit thermal radiation with a Planck spectrum at the Hawking temperature, and analyzes this…
Quantum aspects of spacetime: A quantum optics view of acceleration radiation and black holes
C. R. Ordonez, A. Chakraborty, H. E. Camblong +2
For the centennial of quantum mechanics, we offer an overview of the central role played by quantum information and thermalization in problems involving fundamental properties of s…
Conformal quantum mechanics of causal diamonds: Quantum instability and semiclassical approximation
H. E. Camblong, A. Chakraborty, P. Lopez-Duque +1
Causal diamonds are known to have thermal behavior that can be probed by finite-lifetime observers equipped with energy-scaled detectors. This thermality can be attributed to the t…
Conformal quantum mechanics of causal diamonds: Time evolution, thermality, and instability via path integral functionals
H. E. Camblong, A. Chakraborty, P. Lopez-Duque +1
An observer with a finite lifetime perceives the Minkowski vacuum as a thermal state at temperature , as a result of being constrained…
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…
