Classical axisymmetric gravity in real Ashtekar variables
Rodolfo Gambini, Esteban Mato, Javier Olmedo +1
We formulate axisymmetric general relativity in terms of real Ashtekar--Barbero variables. We study the constraints and equations of motion and show how the Kerr, Schwarzschild and…
A single-world consistent interpretation of quantum mechanics from fundamental time and length uncertainties
Rodolfo Gambini, Luis Pedro García Pintos, Jorge Pullin
Within ordinary ---unitary--- quantum mechanics there exist global protocols that allow to verify that no definite event ---an outcome to which a probability can be associated--- o…
Report on session QG3 of the 15th Marcel Grossmann Meeting
Jorge Pullin, Parampreet Singh
We summarize the talks presented at the QG3 session (loop quantum gravity: cosmology and black holes) of the 15th Marcel Grossmann Meeting held in Rome, Italy on July 1-7 2018.
Gravitation in terms of observables
Rodolfo Gambini, Jorge Pullin
In the 1960's, Mandelstam proposed a new approach to gauge theories and gravity based on loops. The program for gauge theories was completed for Yang--Mills theories by Gambini and…
