The memory equation of a characteristic function in surface diffusion
S. Miret-Artés
The decay of a density wave, the Fourier component of the adparticle density seen by a coherent probe, obeys in an interacting adlayer an exact memory equation of Mori's form, dete…

Surface diffusion with lateral interactions: a closed-form intermediate scattering function of an Ising adlayer from the memory-equation formalism
S. Miret-Artés
The intermediate scattering function and its value at zero time, which is the static structure factor, are both characteristic functions. An exact equation of motion for the ISF ca…
