Universal role of curvature in vacuum entanglement
Hari K, Subhajit Barman, Dawood Kothawala
We highlight some universal features concerning the role of spacetime curvature in the entanglement induced between quantum probes coupled to a quantum field in a suitable vacuum s…
Rotating detectors in dS/AdS spacetimes
Hari. K, Dawood Kothawala
We analyse several aspects of detectors with uniform acceleration and uniform rotation in de Sitter () and anti-de Sitter () spacetimes, focusing particularly on…
Limits of a non-local quantum spacetime
Dawood Kothawala
A generic implication of incorporating gravitational effects in the analysis of quantum measurements is the existence of a zero-point length of spacetime. This requires an inherent…
Synge's World function and the quantum spacetime
Dawood Kothawala
All our observations that characterise space and time are expressed in terms of non-local, bi-tensorial objects such as geodesic intervals between events and two-point (Green) func…
Decoherence due to Spacetime Curvature
Raghvendra Singh, Kabir Khanna, Dawood Kothawala
There has been considerable interest over the past years in investigating the role of gravity in quantum phenomenon such as entanglement and decoherence. In particular, gravitation…
