Quantum reduced loop gravity: extension to gauge vector field
Jakub Bilski, Emanuele Alesci, Francesco Cianfrani +2
Within the framework of Quantum Reduced Loop Gravity we quantize the Hamiltonian for a gauge vector field. The regularization can be performed using tools analogous to the ones ado…
Non Bunch Davies group coherent states, and their quantum signatures in CMB observables
Pietro Dona, Antonino Marciano
We approach the problem of finding generalized states for matter fields in a de Sitter universe, moving from a group theoretical point of view. This has profound consequences for c…
A note on the semiclassicality of cosmological perturbations
Pietro Dona, Antonino Marciano
Moving from the consideration that matter fields must be treated in terms of their fundamental quantum counterparts, we show straightforward arguments, within the framework of ordi…
Dark Energy and Dark Matter from Yang-Mills Condensate and the Peccei-Quinn mechanism
Andrea Addazi, Pietro Donà, Antonino Marcianò
We analyze a model of cold axion Dark Matter weakly coupled with a dark gluon condensate, reproducing Dark Energy. We first review how to recover the Dark Energy behavior using the…
