Clockwork Inflation
  We investigate the recently proposed clockwork mechanism delivering light
degrees of freedom with suppressed interactions and show, with various
examples, that it can be efficiently implemented in inflationary scenarios to
generate flat inflaton potentials and small density perturbations without
fine-tunings. We also study the clockwork graviton in de Sitter and,
interestingly, we find that the corresponding clockwork charge is
site-dependent. As a consequence, the amount of tensor modes is generically
suppressed with respect to the standard cases where the clockwork set-up is not
adopted. This point can be made a virtue in resurrecting models of inflation
which were supposed to be ruled out because of the excessive amount of tensor
modes from inflation.
