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…
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…
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…
Emergence of odd elasticity in a microswimmer using deep reinforcement learning
Li-Shing Lin, Kento Yasuda, Kenta Ishimoto +1
We use the Deep Q-Network with reinforcement learning to investigate the emergence of odd elasticity in an elastic microswimmer model. For an elastic microswimmer, it is challengin…
Reciprocal microswimming in fluctuating and confined environments
Yoshiki Hiruta, Kenta Ishimoto
From bacteria and sperm cells to artificial microrobots, self-propelled microscopic objects at low Reynolds numbers often perceive fluctuating mechanical and chemical stimuli and c…
Odd elastohydrodynamics: non-reciprocal living material in a viscous fluid
Kenta Ishimoto, Clément Moreau, Kento Yasuda
Motility is a fundamental feature of living matter, encompassing single cells and collective behavior. Such living systems are characterized by non-conservativity of energy and a l…
Odd elasticity of a catalytic micromachine
Akira Kobayashi, Kento Yasuda, Kenta Ishimoto +4
We perform numerical simulations of a model micromachine driven by catalytic chemical reactions. Our model includes a mechano-chemical coupling between the structural variables and…
Onsager's variational principle for nonreciprocal systems with odd elasticity
Li-Shing Lin, Kento Yasuda, Kenta Ishimoto +2
Using Onsager's variational principle, we derive dynamical equations for a nonequilibrium active system with odd elasticity. The elimination of the extra variable that is coupled t…
Time-correlation functions for odd Langevin systems
Kento Yasuda, Kenta Ishimoto, Akira Kobayashi +4
We investigate the statistical properties of fluctuations in active systems that are governed by non-symmetric responses. Both an underdamped Langevin system with an odd resistance…
The effects of rapid yawing on simple swimmer models and planar Jeffery's orbits
Benjamin J. Walker, Kenta Ishimoto, Eamonn A. Gaffney +2
Over a sufficiently long period of time, or from an appropriate distance, the motion of many swimmers can appear smooth, with their trajectories appearing almost ballistic in natur…
Self-organized swimming with odd elasticity
Kenta Ishimoto, Clément Moreau, Kento Yasuda
We theoretically investigate self-oscillating waves of an active material, which have recently been introduced as a non-symmetric part of the elastic moduli, termed odd elasticity.…
Control and controllability of microswimmers by a shearing flow
Clément Moreau, Kenta Ishimoto, Eamonn A. Gaffney +1
With the continuing rapid development of artificial microrobots and active particles, questions of microswimmer guidance and control are becoming ever more relevant and prevalent.…
