Numerical test of finite-barrier corrections for the hopping rate in the underdamped regime
Abstract
It is shown that the large differences, which have been found in the underdamped regime, between analytical calculations and exact numerical results for the hopping rate in a periodic potential are essentially due to finite-barrier effects. In fact, if finite-barrier corrections are taken into account, the analytical results turn out to be in quite good agreement with the exact ones in the full damping range below the turnover point.
