Time Uncertainty in Quantum Gravitational Systems
J. Fernando Barbero G., Guillermo A. Mena Marugan, Eduardo J. S. Villaseñor
It is generally argued that the combined effect of Heisenberg principle and general relativity leads to a minimum time uncertainty. Most of the analyses supporting this conclusion…
Lorentz Violations and Euclidean Signature Metrics
J. Fernando Barbero G., Eduardo J. S. Villaseñor
We show that the families of effective actions considered by Jacobson et al. to study Lorentz invariance violations contain a class of models that represent pure General Relativity…
Microcausality and Quantum Cylindrical Gravitational Waves
J. Fernando Barbero G., Guillermo A. Mena Marugan, Eduardo J. S. Villaseñor
We study several issues related to the different choices of time available for the classical and quantum treatment of linearly polarized cylindrical gravitational waves. We pay esp…
