Description

In this talk we revisit the technique of semiclassical effective dynamics, focusing on the evaluation of the Poisson structure of central moments that encode quantum corrections. A systematic, pedagogical, and efficient algorithm for deriving these structures is presented. The resulting formulae are applied to a broad class of isotropic cosmological models, incorporating locally observable configuration variables for matter fields. This approach enables the formulation of a consistent and nontrivial procedure for the removal of the fiducial cell (infrared regulator) in models describing spatially noncompact spacetimes.
