Amplitude of jump motion signatures in classical vibration-jump dynamic
Peter S. M. Townsend, John Ellis
The classical Langevin dynamics of a particle in a periodic potential energy landscape are studied via the intermediate scattering function (ISF). By construction, the particle per…

The intermediate scattering function for quasi-elastic scattering in the presence of memory friction
Peter Stephen Morris Townsend, David James Ward
We derive an analytical expression for the intermediate scattering function of a particle on a flat surface obeying the Generalised Langevin Equation, with exponential memory frict…
