Non-reciprocal Phase Separations with Non-conserved Order Parameters
Maoji Liu, Zhanglin Hou, Hiroyuki Kitahata +2
We numerically investigate the phase separation dynamics of the non-reciprocal Allen-Cahn model in which two non-conserved order parameters are coupled. The system exhibits several…
Activity Induced Diffusion Recovery in Crowded Colloidal Suspension
Arnab Maiti, Yuki Koyano, Hiroyuki Kitahata +1
We show that the force generated by active enzyme molecules are strong enough to influence the dynamics of their surroundings under artificial crowded environments. We measured the…
Mathematical modeling for the synchronization of two interacting active rotors
Hiroyuki Kitahata, Yuki Koyano
We investigate the synchronization of active rotors. A rotor is composed of a free-rotating arm with a particle that releases a surface-active chemical compound. It exhibits self-r…
Aspect-ratio-dependent void formation in active rhomboidal and elliptical particle systems
Motoya Suzaka, Hiroaki Ito, Hiroyuki Kitahata
We execute a numerical simulation on active nematics with particles interacting by an excluded volume effect. The systems with rhomboidal particles and that with elliptical particl…
Reaction-induced molecular dancing and boosted diffusion of enzymes
Hiroyuki Kitahata, Alexander S. Mikhailov
A novel mechanism of reaction-induced active molecular motion, not involving any kind of self-propulsion, is proposed and analyzed. Because of the momentum exchange with the surrou…
Two-dimensional hydrodynamic simulation for synchronization in coupled density oscillators
Nana Takeda, Hiroaki Ito, Hiroyuki Kitahata
A density oscillator is a fluid system in which oscillatory flow occurs between different density fluids through the pore connecting them. We investigate the synchronization in cou…
