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…

Average mutual information for random fermionic Gaussian quantum states
Lucas Hackl, Mario Kieburg, Joel Maldonado
Studying the typical entanglement entropy of a bipartite system when averaging over different ensembles of pure quantum states has been instrumental in different areas of physics,…
