Contribution

It provides a theoretical framework for analyzing coupled rotational diffusion in particle chains using the Smoluchowski equation.

Findings

Explored hydrodynamic interactions in the lubrication limit.

Provided a basis for experimental measurement of rotational dynamics.

Abstract

We study the coupled rotational diffusion in a two-particle chain on the basis of a Smoluchowski equation and calculate time-correlation functions that are measurable in an experiment. This might be used to explore hydrodynamic interactions in the limit where lubrication theory is valid.
