Multi-field inflation from single-field models
Martin Bojowald, Suddhasattwa Brahma, Sean Crowe +2
Quantization implies independent degrees of freedom that do not appear in the classical theory, given by fluctuations, correlations, and higher moments of a state. A systematic der…
Quantum Higgs Inflation
Martin Bojowald, Suddhasattwa Brahma, Sean Crowe +2
The Higgs field is an attractive candidate for the inflaton because it is an observationally confirmed fundamental scalar field. Importantly, it can be modeled by the most general…
General-relativistic spin system
Danilo Artigas, Jakub Bilski, Sean Crowe +2
The models of spin systems defined on Euclidean space provide powerful machinery for studying a broad range of condensed matter phenomena. While the non-relativistic effective desc…
Quantum fluctuations of the compact phase space cosmology
Danilo Artigas, Sean Crowe, Jakub Mielczarek
In the recent article Phys. Rev. D 100, no. 4, 043533 (2019) a compact phase space generalization of the flat de Sitter cosmology has been proposed. The main advantages of the comp…
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…
