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…
