Adiabatic vacua from linear complex structures
Eugenio Bianchi, Yusuf Ghelem, Lucas Hackl
Adiabatic vacua play a central role in quantum fields in cosmological spacetimes, where they serve as distinguished initial conditions and as reference states for the renormalizati…
Loop expansion and the bosonic representation of loop quantum gravity
Eugenio Bianchi, Jonathan Guglielmon, Lucas Hackl +1
We introduce a new loop expansion that provides a resolution of the identity in the Hilbert space of loop quantum gravity on a fixed graph. We work in the bosonic representation ob…
Squeezed vacua in loop quantum gravity
Eugenio Bianchi, Jonathan Guglielmon, Lucas Hackl +1
We introduce squeezed vacua in loop quantum gravity, a new overcomplete basis of states that contain prescribable correlations between geometric operators. We study the behavior of…
Entanglement time in the primordial universe
Eugenio Bianchi, Lucas Hackl, Nelson Yokomizo
We investigate the behavior of the entanglement entropy of space in the primordial phase of the universe before the beginning of cosmic inflation. We argue that in this phase the e…
