Quantum-gravity effects for excited states of inflationary perturbations
  We generalize former findings regarding quantum-gravitational corrections
arising from a canonical quantization of a perturbed FLRW universe during
inflation by considering an initial state for the scalar and tensor
perturbations that generalizes the adiabatic vacuum state and allows us to
consider the scenario that the perturbation modes start their evolution in an
excited state. Our result shows that the quantum-gravitationally corrected
power spectra get modified by pre-factors including the excitation numbers.
