Intermediate scattering function of Brownian particles in a tilted cosine potential
Regina Rusch, Thomas Franosch
We solve the Fokker-Planck equation for a Brownian particle in a tilted cosine potential and derive the intermediate scattering function (ISF), which captures the full spatio-tempo…

Intermediate scattering function of colloids in a periodic laser field
Regina Rusch, Yasamin Mohebi Satalsari, Angel B. Zuccolotto-Bernez +2
We investigate the dynamics of individual colloidal particles in a one-dimensional periodic potential using the intermediate scattering function (ISF) as a key observable. We elabo…

Intermediate scattering function of a gravitactic circle swimmer
Regina Rusch, Oleksandr Chepizhko, Thomas Franosch
We analyze gravitaxis of a Brownian circle swimmer by deriving and characterizing analytically the experimentally measurable intermediate scattering function (ISF). To solve the as…
