If you have a question about this talk, please contact Pietro Benetti Genolini. I will discuss non-perturbative quantum gravity effects relevant in the early universe cosmology. We will study two-dimensional toy models of inflation and discover that geometries that connect the bra with the ket of the wave function of the universe, bra-ket wormholes, have to be included for consistency of the models. This has potential consequences for basic cosmological observables, like the power spectrum of primordial fluctuations. This talk is part of the Quantum Fields and Strings Seminars series.
