Observables are glocal
Emil Broukal, Andrea Di Biagio, Eugenio Bianchi +1
We show that the problem of observables can be fully resolved for background independent theories defined on graphs, through the explicit construction of complete observables. The…
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…
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 meas…
A Maximum Entropy Conjecture for Black Hole Mergers
Monica Rincon-Ramirez, Nathan K. Johnson-McDaniel, Eugenio Bianchi +3
The final state of a binary black hole merger is predicted with high precision by numerical relativity, but could there be a simple thermodynamic principle within general relativit…
Adiabatic vacua from linear complex structures
Eugenio Bianchi, Yusuf Ghelem, Lucas Hackl
Adiabatic vacua play a central role in quantum fields in cosmological spacetimes, where they serve as distinguished initial conditions and as reference states for the renormalizati…
