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…

Spinfoams, -duality and parity violation in primordial gravitational waves
Eugenio Bianchi, Monica Rincon-Ramirez
The Barbero-Immirzi parameter appears as a coupling constant in the spinfoam dynamics of loop quantum gravity. In this work, we highlight that can be understood as a measur…
