Probing Spacetime Topology and Superposition with Accelerated Detectors
P. Poopathysankar, Lucas Hackl, Anwesha Chakraborty
We study entanglement harvested by Unruh DeWitt detectors following Rindler trajectories in compactified and superposed Minkowski spacetime. We consider different directions of acc…

Random pure Gaussian states and Hawking radiation
Erik Aurell, Lucas Hackl, PaweÅ Horodecki +2
A black hole evaporates by Hawking radiation. Each mode of that radiation is thermal. If the total state is nevertheless to be pure, modes must be entangled. Estimating the minimum…

Entanglement harvesting in quantum superposed spacetime
Anwesha Chakraborty, Lucas Hackl, Magdalena Zych
We investigate the phenomenon of entanglement harvesting for a spacetime in quantum superposition, using two Unruh-DeWitt detectors interacting with a quantum scalar field where th…
