Extended Onsager's variational principle for nonlinear chemical reaction kinetics in active matter
Xinpeng Xu, Changhao Li, Zhongqiang Xiong +3
Onsager's variational principle (OVP) constructs dissipative dynamics from free energy, dissipation, and input power, but deterministic rate laws alone do not identify fluctuations…
Geometric formulation of state-dependent Langevin dynamics using scalar free energy
Kento Yasuda, Zhongqiang Xiong, Zhanglin Hou +3
Stochastic dynamics with state-dependent diffusion arise broadly in confined, anisotropic, and hydrodynamically coupled systems. The conventional Langevin equation contains a spuri…
Covariant Onsager and Onsager-Machlup principles for active and inertial dynamics
Kento Yasuda, Bin Zheng, Zhongqiang Xiong +5
The Onsager principle provides a variational route to the phenomenological equations of dissipative dynamics through the minimization of the Rayleighian. We develop a covariant for…
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…
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…
