The projector on physical states in loop quantum gravity
Carlo Rovelli
We construct the operator that projects on the physical states in loop quantum gravity. To this aim, we consider a diffeomorphism invariant functional integral over scalar function…

The fermionic contribution to the spectrum of the area operator in nonperturbative quantum gravity
Merced Montesinos, Carlo Rovelli
The role of fermionic matter in the spectrum of the area operator is analyzed using the Baez--Krasnov framework for quantum fermions and gravity. The result is that the fermionic c…
