We apply a Langevin model by imposing additive and multiplicative noises to study thermally activateddiffusion over a fluctuating barrier in underdamped dynamics.
Abstract: We apply a Langevin model by imposing additive and multiplicative noises to study thermally activateddiffusion over a fluctuating barrier in underdamped dynamics.
The results indicate that the diffusion process of oxygen and nitrogen in carbon molecular sieve is activated, such an process may be represented by the dual diffusion resistance model.
