Bond-number-controlled durability of cohesive granular materials under repeated vibration
Hikari Yokota, Rei Kurita
Cohesive granular materials derive their mechanical stability not only from the strength of individual interparticle bonds but also from the number of bonds forming the load-bearin…
Fluid-structure coupling governs a dynamic transition in foam scraping
Rei Kurita, Masaya Endo
Foam scraping exhibits a dynamic transition between a slip state, in which the foam moves beneath a plate, and a scraping state, in which the foam is expelled from the confined reg…
Geometric control of powder jet dynamics and energy dissipation
Kazuya U. Kobayash, Komei Jinbo, Riku Kodama +2
Applying an impulsive force to a powder layer shaped with a concave surface generates a sharp powder jet. This phenomenon has been proposed as a method for evaluating the flowabili…
Hidden Structural Control of Solvent Transport under Soft Jamming
Kento Tamaki, Naoya Yanagisawa, Rei Kurita
Transport in soft jammed materials is often described as fluid motion through a fixed structure, leading naturally to capillary based descriptions. This picture appears particularl…
Critical-like phenomenon in scraping of jamming systems
Masaya Endo, Rei Kurita
In jamming systems like colloids, emulsions, foams, and biological tissues, significant deformation is essential for processes such as material scraping or wound self-healing. To a…
Spreading of foam on a substrate
Masaya Endo, Marie Tani, Rei Kurita
Foam is an industrially important form of matter, commonly deployed to clean objects and even our own skin, thanks to its ability to absorb oil and particles into its interior. To…
Gel-like granular materials with high durability and high deformability
Honoka Fujio, Hikari Yokota, Marie Tani +1
Building materials such as concretes and mortar are formed by solidifying granular slabs. Such materials are often fractured by giant forces such as during earthquakes, leading to…
Selective 3-dimensional patterning during phase separation of a continuously laminated layer
Rikuya Ishikawa, Marie Tani, Rei Kurita
Control over the physical properties of materials is ubiquitously required in many fields. One means by which this can be achieved is controlling the internal structure of multi-co…
Glassy atomic vibrations and blurry electronic structures created by local structural disorders in high-entropy metal telluride superconductors
Yoshikazu Mizuguchi, Hidetomo Usui, Rei Kurita +10
The motivation of this work is our recent observation of the robustness of superconductivity in a High-entropy (HE) superconductor Ag0.2In0.2Sn0.2Pb0.2Bi0.2Te (CsCl-type) to extern…
Measuring every particle's size from three-dimensional imaging experiments
Rei Kurita, Eric R. Weeks
Often experimentalists study colloidal suspensions that are nominally monodisperse. In reality these samples have a polydispersity of 4-10%. At the level of an individual particle,…
Incompressibility of polydisperse random close packed colloidal particles
Rei Kurita, Eric R. Weeks
We use confocal microscopy to study a random close packed sample of colloidal particles. We introduce an algorithm to estimate the size of each particle. Taking into account their…
Experimental study of random close packed colloidal particles
Rei Kurita, Eric R Weeks
A collection of spherical particles can be packed tightly together into an amorphous packing known as "random close packing" (RCP). This structure is of interest as a model for the…
The glass transition of two-dimensional binary soft disk mixtures with large size ratios
Rei Kurita, Eric R. Weeks
We simulate binary soft disk systems in two dimensions, and investigate how the dynamics slow as the area fraction is increased toward the glass transition. The "fragility" quantif…
