The physical hamiltonian in nonperturbative quantum gravity
Carlo Rovelli, Lee Smolin
A quantum hamiltonian which evolves the gravitational field according to time as measured by constant surfaces of a scalar field is defined through a regularization procedure based…

The basis of the Ponzano-Regge-Turaev-Viro-Ooguri model is the loop representation basis
Carlo Rovelli
We show that the Hilbert space basis that defines the Ponzano-Regge- Turaev-Viro-Ooguri combinatorial definition of 3-d Quantum Gravity is the same as the one that defines the Loop…
