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…
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…
