Effective dynamics of quantum fluctuations in field theory: with applications to cosmology
Ding Ding, Zhao Yu, Yidun Wan
We develop a novel framework for describing quantum fluctuations in field theory, with a focus on cosmological applications. Our method uniquely circumvents the use of operator/Hil…
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…
Canonical description of cosmological backreaction
Martin Bojowald, Ding Ding
Canonical methods of quasiclassical dynamics make it possible to go beyond a strict background approximation for cosmological perturbations by including independent fields such as…
Deformed covariance in spherically symmetric vacuum models of loop quantum gravity: Consistency in Euclidean and self-dual gravity
Martin Bojowald, Suddhasattwa Brahma, Ding Ding +1
Different versions of consistent canonical realizations of hypersurface deformations of spherically symmetric space-times have been derived in models of loop quantum gravity, modif…
