Reciprocal Cost on the Positive Rationals
Jonathan Washburn, Sebastian Pardo-Guerra, Milan Zlatanović
We study nonnegative solutions of the reciprocal cost law on the positive rationals and determine which of them admit regular extensions to the positive reals. Using the substituti…

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…

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…
