Minisuperspace results for causal dynamical triangulations
Bekir Baytas, Martin Bojowald, Sean Crowe +1
Detailed applications of minisuperspace methods are presented and compared with results obtained in recent years by means of causal dynamical triangulations (CDTs), mainly in the f…
Equivalence of models in loop quantum cosmology and group field theory
Bekir Baytas, Martin Bojowald, Sean Crowe
The paradigmatic models often used to highlight cosmological features of loop quantum gravity and group field theory are shown to be equivalent, in the sense that they are differen…
Effective potentials from semiclassical truncations
Bekir Baytas, Martin Bojowald, Sean Crowe
Canonical variables for the Poisson algebra of quantum moments are introduced here, expressing semiclassical quantum mechanics as a canonical dynamical system that extends the clas…
Canonical Tunneling Time in Ionization Experiments
Bekir Baytas, Martin Bojowald, Sean Crowe
Canonical semiclassical methods can be used to develop an intuitive definition of tunneling time through potential barriers. An application to atomic ionization is given here, cons…
Faithful realizations of semiclassical truncations
Bekir Baytas, Martin Bojowald, Sean Crowe
Realizations of algebras in terms of canonical or bosonic variables can often be used to simplify calculations and to exhibit underlying properties. There is a long history of usin…
