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 matrix prediction of average entanglement entropy in non-Abelian symmetry sectors
Anwesha Chakraborty, Lucas Hackl, Mario Kieburg
We study the average bipartite entanglement entropy of Haar-random pure states in quantum many-body systems with global symmetry, constrained to fixed total spin $…

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…
