Radiative corrections to the Lorentzian EPRL spin foam propagator
Pietro Donà, Pietropaolo Frisoni, Edward Wilson-Ewing
We numerically estimate the divergence of several two-vertex diagrams that contribute to the radiative corrections for the Lorentzian EPRL spin foam propagator. We compute the ampl…
Observational constraints on anisotropies for bouncing alternatives to inflation
Ivan Agullo, Javier Olmedo, Edward Wilson-Ewing
We calculate how primordial anisotropies in the background space-time affect the evolution of cosmological perturbations for bouncing alternatives to inflation, like ekpyrosis and…
On the fate of quantum black holes
Viqar Husain, Jarod George Kelly, Robert Santacruz +1
We study the quantum dynamics of the Lemaître-Tolman-Bondi space-times using a polymer quantization prescription based on loop quantum cosmology that incorporates fundamental discr…
