Diffusion in the systems with low dissipation: Exponential growth with temperature drop

We study the diffusion of particles exposed to the external constant force in the periodic spatial potential by means of computer modelling. It has been shown that in the underdamped case the diffusion coefficient is increased exponentially with a drop in temperature in a certain interval of F. The...

Zusammenfassung:We study the diffusion of particles exposed to the external constant force in the periodic spatial potential by means of computer modelling. It has been shown that in the underdamped case the diffusion coefficient is increased exponentially with a drop in temperature in a certain interval of F. The physical reasons for such an abnormal behavior have been analyzed.
