On the consistency of the constraint algebra in spin network quantum gravity
Rodolfo Gambini, Jerzy Lewandowski, Donald Marolf +1
We point out several features of the quantum Hamiltonian constraints recently introduced by Thiemann for Euclidean gravity. In particular we discuss the issue of the constraint alg…

Large quantum gravity effects: backreaction on matter
Rodolfo Gambini, Jorge Pullin
We reexamine the large quantum gravity effects discovered by Ashtekar in the context of 2+1 dimensional gravity coupled to matter. We study an alternative one-parameter family of c…

Chern--Simons states in spin-network quantum gravity
Rodolfo Gambini, Jorge Griego, Jorge Pullin
In the context of canonical quantum gravity in terms of Ashtekar's new variables, it is known that there exists a state that is annihilated by all the quantum constraints and that…
