Hamiltonian formalism for cosmological perturbations: fixing the gauge
Danilo Artigas, Julien Grain, Vincent Vennin
Cosmological perturbation theory is an example of a gauge theory, where gauge transformations correspond to changes in the space-time coordinate system. To determine physical quant…
Squeezing of light from Planck-scale physics
Danilo Artigas, Killian Martineau, Jakub Mielczarek
In this article, the possibility of generating non-classical light due to Planck-scale effects is considered. For this purpose, a widely studied model of deformation of the Heisenb…
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…
