Fundamental decoherence from relational time in discrete quantum gravity: Galilean covariance
Rodolfo Gambini, Rafael Porto, Jorge Pullin
We have recently argued that if one introduces a relational time in quantum mechanics and quantum gravity, the resulting quantum theory is such that pure states evolve into mixed s…
Dirac-like approach for consistent discretizations of classical constrained theories
Cayetano Di Bartolo, Rodolfo Gambini, Rafael Porto +1
We analyze the canonical treatment of classical constrained mechanical systems formulated with a discrete time. We prove that under very general conditions, it is possible to intro…
Consistent and mimetic discretizations in general relativity
Cayetano Di Bartolo, Rodolfo Gambini, Jorge Pullin
A discretization of a continuum theory with constraints or conserved quantities is called mimetic if it mirrors the conserved laws or constraints of the continuum theory at the dis…
