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 t…
Entanglement Degradation in Causal Diamonds
H. E. Camblong, A. Chakraborty, P. Lopez-Duque +1
Entanglement degradation appears to be a generic prediction in relativistic quantum information whenever horizons restrict access to a region of spacetime. This property has been p…
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…
Thermal effect in a causal diamond: open quantum systems approach
Abhijit Chakraborty, Horacio Camblong, Carlos Ordonez
A static observer with a finite lifetime has causal access to only a limited region of spacetime known as the causal diamond. The presence of an apparent horizon in the causal diam…
Quantum anomaly and thermodynamics of one-dimensional fermions with three-body interactions
Joaquín E. Drut, Joshua R. McKenney, Wilder S. Daza +2
We show that a system of three species of one-dimensional fermions, with an attractive three-body contact interaction, features a scale anomaly directly related to the anomaly of t…
