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…

Neural optimization of the most probable paths of 3D active Brownian particles

Bin Zheng, Zhongqiang Xiong, Changhao Li +7

We develop a variational neural-network framework to determine the most probable path (MPP) of a 3D active Brownian particle (ABP) by directly minimizing the Onsager-Machlup integr…

Taylor Dispersion in Sedimentation of an Axisymmetric Brownian Particle with Centre Offset

Zhongqiang Xiong, Ryohei Seto, Masao Doi

When a non-spherical particle sediments, its velocity generally changes in time as the particle orientation changes in time. This gives extra dispersion of the particle position in…
