Brownian motion of a rod threading through a ring with fixed ring-center
Zhongqiang Xiong, Shigeyuki Komura, Masao Doi
We study the Brownian motion of a rigid rod threading through a small fixed ring while the ring can freely rotate. We derive the distribution function for the sliding displacement…

Bending-Rotation coupling in the viscoelasticity of semiflexible polymers -- Rigorous perturbation analysis from the rod limit
Zhongqiang Xiong, Ryohei Seto, Masao Doi
Brownian motion and viscoelasticity of semiflexible polymers is a subject that has been studied for many years. Still, rigorous analysis has been hindered due to the difficulty in…
