Non-uniform swelling of polyelectrolyte hydrogels: effects of charge regulation
Du Chen, Rudolph Podgornik, David Andelman +4
We investigate the impact of charge regulation (CR) on the non-uniform swelling behavior of polyelectrolyte hydrogels. The Poisson-Boltzmann theory with electro-elastic coupling be…

Fokker-Planck description of an active Brownian particle with rotational inertia
Lingyi Wang, Ziluo Zhang, Zhongqiang Xiong +3
We develop a perturbative framework to calculate the mean-squared displacement (MSD) of active Brownian particles (ABPs) with a finite moment of inertia. Starting from the correspo…

Ornstein-Uhlenbeck information particle: A new candidate of active agent
Xin Song, Xiji Shao, Yanwen Zhu +4
An information particle can acquire active-like motion through transforming the information entropy into effective self-propulsion velocity/force using the attached information eng…
