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…
An Informational Route to Negative Mobility
Ziluo Zhang, Shigeyuki Komura, Zhihong You
Mobility links an applied force to the resulting motion and is generally positive near equilibrium. Far from equilibrium, however, internal energy input can reverse this response.…
Lateral hydrodynamics in supported membranes: The Evans-Sackmann model and its extensions
Yuto Hosaka, David Andelman, Shigeyuki Komura
We review the theoretical development and modern applications of the Evans-Sackmann hydrodynamic model for lateral transport in supported fluid membranes. We first cover the origin…
Electrostatic effects in nano-reactor-confined charge regulated macroions
Manit Klawtanong, Petch Khunpetch, Huaqiong Li +1
We formulate a thermodynamic model of a nano-reactor containing charge-regulated macroions within an electrolyte-permeable enclosure. The model is then formalized within the Poisso…
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…
Analytical response functions for a compressible thin fluid layer with odd viscosity
Abdallah Daddi-Moussa-Ider, Yuto Hosaka, Shigeyuki Komura
Fluids composed of chiral active components can exhibit odd viscosity, a property that breaks time-reversal and parity symmetries. We investigate the hydrodynamic response to monop…
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…
Demon's variational principle for informational active matter
Kento Yasuda, Kenta Ishimoto, Shigeyuki Komura
The interplay between information, dissipation, and control is reshaping our understanding of thermodynamics in feedback-regulated systems. We develop the informational Onsager-Mac…
Thermally driven two-sphere microswimmer with internal feedback control
Jun Li, Ziluo Zhang, Zhanglin Hou +4
We discuss the locomotion of a thermally driven elastic two-sphere microswimmer with internal feedback control that is realized by the position-dependent friction coefficients. In…
Ornstein-Uhlenbeck information swimmers with external and internal feedback controls
Zhanglin Hou, Ziluo Zhang, Jun Li +2
Using an underdamped active Ornstein-Uhlenbeck particle, we propose two information swimmer models having either external or internal feedback control and perform their numerical s…
Diffusive dynamics of charge regulated macro-ion solutions
Bin Zheng, Shigeyuki Komura, David Andelman +1
Onsager's variational principle is generalized to address the diffusive dynamics of an electrolyte solution composed of charge-regulated macro-ions and counterions. The free energy…
Statistical formulation of Onsager-Machlup variational principle
Kento Yasuda, Kenta Ishimoto, Shigeyuki Komura
Onsager's variational principle (OVP) provides us with a systematic way to derive dynamical equations for various soft matter and active matter. By reformulating the Onsager-Machlu…
