Lateral diffusion on a frozen random surface
Takao Ohta, Shigeyuki Komura
The lateral diffusion coefficient of a Brownian particle on a two-dimensional random surface is studied in the quenched limit for which the surface configuration is time-independen…
Simple model of cell crawling
Takao Ohta, Mitsusuke Tarama, Masaki Sano
Based on symmetry consideration of migration and shape deformations, we formulate phenomenologically the dynamics of cell crawling in two dimensions. Forces are introduced to chang…
Dynamics and electro-rheology of sheared immiscible fluid mixtures
Takahiro Sakaue, Kyohei Shitara, Takao Ohta
We analyze the electro-rheological effect in immiscible fluid mixtures with dielectric mismatch. By taking the electric field effect into account, which couples to the dynamics of…
Active crystals and their stability
Andreas M. Menzel, Takao Ohta, Hartmut Löwen
A recently introduced active phase field crystal model describes the formation of ordered resting and traveling crystals in systems of self-propelled particles. Increasing the acti…
Individual and collective dynamics of self-propelled soft particles
M. Tarama, Y. Itino, A. M. Menzel +1
Deformable self-propelled particles provide us with one of the most important nonlinear dissipative systems, which are related, for example, to the motion of microorganisms. It is…
Dynamics of a deformable active particle under shear flow
Mitsusuke Tarama, Andreas M. Menzel, Borge ten Hagen +3
The motion of a deformable active particle in linear shear flow is explored theoretically. Based on symmetry considerations, in two spatial dimensions, we propose coupled nonlinear…
