Unitarity of quantum-gravitational corrections to primordial fluctuations in the Born-Oppenheimer approach
Leonardo Chataignier, Manuel Kraemer
We revisit the calculation of quantum-gravitational corrections to the power spectra of scalar and tensor perturbations in the Born-Oppenheimer approach to quantum gravity. We focu…

Relational observables, reference frames, and conditional probabilities
Leonardo Chataignier
We discuss the construction of relational observables in time-reparametrization invariant quantum mechanics and we argue that their physical interpretation can be understood in ter…
