Amoeboid movement utilizes the shape coupled bifurcation of an active droplet to boost ballistic motion
H. Ebata, Y. Nishigami, H. Fujiwara +2
One of the essential functions of living organisms is spontaneous migration through the deformation of their body, such as crawling, swimming, and walking. Depending on the size of…
A link between anomalous viscous loss and boson peak in soft jammed solids
Yusuke Hara, Ryosuke Matsuoka, Hiroyuki Ebata +2
Soft jammed solids exhibit intriguing mechanical properties, while their linear response is elusive. In particular, foams and emulsions generally reveal anomalous viscous loss with…
Non-Equilibrium Fluidization of Dense Active Suspension
Yujiro Sugino, Hiroyuki Ebata, Yoshiyuki Sowa +2
We investigate dense suspensions of swimming bacteria prepared in a nutrient-exchange chamber. Near the pellet concentration, nonthermal fluctuations showed notable agreement betwe…
Convection of mono-disperse particles in a highly filled rotating cylinder
Shoichi Yoneta, Hiroyuki Ebata, Shio Inagaki
We investigate the occurrence of spontaneous convection in a coaxial cylinder highly filled with mono-disperse spheres. To analyze the flow field non-invasively, initial pulses con…
Segregation patterns in rotating cylinders determined by the size difference, density ratio, and cylinder diameter
Kurumi Kondo, Hiroyuki Ebata, Shio Inagaki
Granular materials often segregate under mechanical agitation, which differs from the expectation of mixing. It is well known that a bidisperse mixture of granular materials in a p…
Self-replicating segregation patterns in horizontally vibrated binary mixture of granules
Hiroyuki Ebata, Shio Inagaki
When granular mixtures of different sizes are fluidized, each species spontaneously separates and condenses to form patterns. Although granular segregation has been extensively stu…
