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…
Canonical quantization of constrained theories on discrete space-time lattices
Cayetano Di Bartolo, Rodolfo Gambini, Jorge Pullin
We discuss the canonical quantization of systems formulated on discrete space-times. We start by analyzing the quantization of simple mechanical systems with discrete time. The qua…
