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…
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 optics meets black hole thermodynamics via conformal quantum mechanics: II. Thermodynamics of acceleration radiation
A. Azizi, H. E. Camblong, A. Chakraborty +2
The thermodynamics of ``horizon brightened acceleration radiation'' (HBAR), due to a random atomic cloud freely falling into a black hole in a Boulware-like vacuum, is shown to mim…
Quantum optics meets black hole thermodynamics via conformal quantum mechanics: I. Master equation for acceleration radiation
A. Azizi, H. E. Camblong, A. Chakraborty +2
A quantum-optics approach is used to study the nature of the acceleration radiation due to a random atomic cloud falling freely into a generalized Schwarzschild black hole through…
Acceleration radiation of an atom freely falling into a Kerr black hole and near-horizon conformal quantum mechanics
A. Azizi, H. E. Camblong, A. Chakraborty +2
An atom falling freely into a Kerr black hole in a Boulware-like vacuum is shown to emit radiation with a Planck spectrum at the Hawking temperature. For a cloud of falling atoms w…
Near-horizon aspects of acceleration radiation by free fall of an atom into a black hole
H. E. Camblong, A. Chakraborty, C. R. Ordonez
A two-level atom freely falling towards a Schwarzschild black hole was recently shown to detect radiation in the Boulware vacuum in an insightful paper [M. O. Scully et al., Proc.…
