Effective relational dynamics of a nonintegrable cosmological model
Philipp A Hoehn, Emilia Kubalova, Artur Tsobanjan
We apply the effective approach to evaluating semiclassical relational dynamics to the closed Friedman--Robertson--Walker cosmological model filled with a minimally coupled massive…
Effective relational dynamics
Philipp A. Hoehn
We provide a synopsis of an effective approach to the problem of time in the semiclassical regime. The essential features of this new approach to evaluating relational quantum dyna…
Canonical formalism for simplicial gravity
Philipp A. Hoehn
We summarise a recently introduced general canonical formulation of discrete systems which is fully equivalent to the covariant formalism. This framework can handle varying phase s…
Canonical simplicial gravity
Bianca Dittrich, Philipp A Hoehn
A general canonical formalism for discrete systems is developed which can handle varying phase space dimensions and constraints. The central ingredient is Hamilton's principal func…
