Typical entanglement entropy with charge conservation
Eugenio Bianchi, Pietro DonÃ, Erick Muiño
We consider a many-body Hilbert space with a fixed global charge and show that the typical entanglement entropy of a subsystem, at the leading and subleading order in the thermodyn…

Spinfoam tunneling of quantum geometries in angle variables
Pietro DonÃ, Hal M. Haggard, Carlo Rovelli +2
Tunneling processes offer a promising path for finding signatures of quantum gravity. While tunneling of geometry has long been recognized in the literature, few detailed analyses…

Non-abelian symmetry-resolved entanglement entropy
Eugenio Bianchi, Pietro Dona, Rishabh Kumar
We introduce a mathematical framework for symmetry-resolved entanglement entropy with a non-abelian symmetry group. To obtain a reduced density matrix that is block-diagonal in the…
