      abstract     = {We investigate the production of axion quanta during the
                      early universe evolution of an axion-like field rolling down
                      a wiggly potential. We compute the growth of quantum
                      fluctuations and their back-reaction on the homogeneous
                      zero-mode. We evaluate the transfer of kinetic energy from
                      the zero mode to the quantum fluctuations and the conditions
                      to decelerate the axion zero-mode as a function of the
                      Hubble rate, the slope of the potential, the size of the
                      barriers and the initial field velocity. We discuss how
                      these effects impact the relaxion mechanism.},
